Board seeks to invalidate 6B worth of Puerto Ricos debt

first_imgSAN JUAN, Puerto Rico — A federal control board that oversees Puerto Rico’s finances is asking a court to invalidate more than $6 billion worth of debt issued by the U.S. territory.The board announced late Monday that the debt includes all general obligation bonds issued in 2012 and 2014 in “clear violation” of debt limits established by Puerto Rico’s Constitution. It also said the debt issued violates balanced budget requirements because the money was used to finance deficit spending.The board’s finding comes after a lengthy investigation that began in September 2017 of all debt issued by Puerto Rico.Economist Jose Caraballo told The Associated Press on Tuesday that the board’s decision is a milestone.It is unclear when a judge would rule on the motion that Caraballo said gives the government bargaining power.The Associated Presslast_img read more

CID recovers huge cache of explosives in Bankura

first_imgKolkata: The state Criminal Investigation Department (CID) has seized a huge quantity of explosive materials from Saltora in Bankura. However, CID sleuths were unable to secure any arrest as the accused persons had fled the scene just before police arrived.According to CID sources, sleuths got a tip on Wednesday that a huge quantity of explosive materials was being stored somewhere in Saltora. Working on the information, sleuths came to know about a village called Kastora in Saltora in the evening. Also Read – Centuries-old Durga Pujas continue to be hit among revellersImmediately, a CID team assisted by local police raided the village. During the search operation a warehouse was found, which was filled with sacks and cartons. After opening the cartons, sleuths were stunned to see the explosive materials. The CID team also spotted an abandoned SUV and a bike near the warehouse. During the ensuing search and seizure procedure, a huge consignment of explosives was recovered. During documentation, CID personnel found 52,500 pieces of electric detonators, 106 cartons of gelatin sticks (power gel) and 133 sacks of ammonium nitrate. The abandoned SUV and bike were also seized. Sleuths are trying to identify the owners of the vehicles. During investigation sleuths came to know that the explosive materials were being procured from Orissa, Telangana and Jharkhand. It is suspected that the explosive materials might have been procured for use in illegal stone quarries. However, all aspects are being checked to ascertain whether any anti-national movement was being organised in the area.last_img read more

UN human rights chief urges Nepals Government and rebels to sign rights

Speaking in Kathmandu, the capital, at the end of a three-day visit, High Commissioner for Human Rights Louise Arbour said the Nepalese people were being subjected to violence and brutality on a staggering scale as a result of the armed conflict.Widespread disappearances, executions and torture must come to an end immediately, she added, calling for effective and credible measures to bring to account those responsible for such acts.In December, the UN Commission on Human Rights’ Working Group on Enforced or Involuntary Disappearances called on the Government to institute such measures as a total ban on incommunicado detention and full protection for human rights workers. Although the group’s mandate is restricted to the obligations of state authorities, it also called on the Maoists to respect human rights. read more

Annans Special Representative meets group in TimorLeste in effort to end dispute

Sukehiro Hasegawa joined Timor-Leste’s Foreign Minister, José Ramos-Horta, who has also been given the Defence Ministry portfolio, in the visit to Gleno, in the nation’s west, to meet with leaders claiming to speak for the people of 10 western districts in their demands for the dismissal of Prime Minister Mari Alkatiri, a UN spokesman told reporters.Mr. Hasegawa “reported telling the meeting that if a process of transition is attempted with violence, then many more people will suffer and leaders may not escape responsibility,” said UN Spokesman Stephane Dujarric, adding that the meeting was part of a series that the Special Representative has undertaken to bring a peaceful end to the recent disturbances in Timor-Leste.On the humanitarian front, UN agencies report that food has been safely supplied to camps in districts to the west and east of Dili, as the combined assistance to more than 100,000 displaced persons reaches further from the capital. The food is supplied by the Government and the UN World Food Programme (WFP) and delivered in trucks provided by the International Organization for Migration.The UN refugee agency (UNHCR) also reports that its airlift of family tents, plastic sheets, and jerry cans has arrived in Dili and is to be moved out to the camps, which have been set up to care for the displaced who have been uprooted in recent weeks through turmoil caused by the dismissal of a third of the armed forces of the tiny country that the UN shepherded to independence from Indonesia in 2002.Mr. Dujarric also told reporters that Secretary-General Kofi Annan’s Special Envoy to Timor-Leste, Ian Martin, is wrapping up his meetings with various Timorese leaders today and would brief the Secretary-General and the Security Council when he comes to New York later this week.Asked about the growing call for UN peacekeepers to return to the country, the spokesman said that after the briefing from Mr. Martin the Security Council would then have to discuss what kind of posture the world body should have in the country. The mandate for the UN mission in Timor-Leste is due to expire on 20 June.Last week, Mr. Annan broadcast a video message to the people of Timor-Leste – the newest Member State of the UN – calling on them not to despair but to “stand up against anyone who tries to divide you on regional or ethnic lines.” read more

Serving Is A Disadvantage In Some Olympic Sports

Table tennisMen’s doubles51 VolleyballMen’s34 BadmintonMen’s singles52 In five Olympic sports, with medals in 18 events up for grabs, a net separates players from their opponents. In each case, before a point can get underway, someone has to serve. On a crucial point, as you watch the medal rounds of badminton and volleyball this weekend, would you rather see your team start with the ball or shuttlecock in its court or in its opponent’s?I tried to find out. It turns out the data isn’t readily available.1A word on the data. Ideally the table that follows would show complete data for every sport. But the Olympics website doesn’t publish comprehensive stats for any of these sports. And press contacts for each of the sport’s international federations either didn’t respond to inquiries or said they couldn’t help with the data. So for each sport, I dug through box scores — in badminton’s case, liberating serve stats from PDFs, and for volleyball, by parsing play-by-plays. I grabbed data for just two or three days of competition in each sport, generally including preliminary stages and knockout stages in which each discipline (singles, doubles, mixed) was competing. Even that wasn’t easy. Alan Reifman, the Texas Tech University professor known for his hot-hand sports analysis who is also a volleyball analyst, tried parsing two games of one volleyball match at my request, and sent me his worksheet. It’s below. But after digging through PDFs and doing a lot of data entry and copy and pasting, I got data for hundreds of matches and thousands of points across 18 variations on the theme of serving. I was looking for how often the player or team that serves ends up winning the point. The conclusion: In tennis, the serve is a weapon. In badminton and table tennis, it’s just a way to get the point started. And in volleyball, it’s a vulnerability. Table tennisMen’s singles53 TennisWomen’s singles57 SPORTEVENTSERVE SUCCESS RATE TennisMen’s doubles65% Table tennisWomen’s singles53 Table tennisWomen’s doubles50 BadmintonWomen’s singles55 Tennis servers have an advantage at the 2016 Olympics; volleyball servers don’t TennisWomen’s doubles56 2016 Olympics data for matches from 2-3 days of preliminary and knockout play for each eventSources:, BadmintonMixed doubles46 Beach volleyballWomen’s35 BadmintonMen’s doubles46 BadmintonWomen’s doubles45 Beach volleyballMen’s32 TennisMen’s singles63 TennisMixed doubles64 VolleyballWomen’s38 The sports divide into a few tiers of serving advantages.Tennis is at the top. Within tennis, the serve is a bigger weapon for men than for women, in part because men are taller than women, on average, and so they can hit down on the ball with less risk. And the serve is more valuable in doubles than in singles, because the returner is trying to avoid the server’s partner and so has to aim for a narrower window than in singles. So at the very top of the server pyramid is men’s doubles, followed by mixed doubles — a man is serving in at least half of the games — and men’s singles. Then come women’s singles and doubles, where the server’s advantage is slightly smaller because of returners’ comparative advantage in the women’s game.In badminton and table tennis, it doesn’t matter all that much who’s serving. But there are some nuances. In both sports, servers do better in singles than in doubles. This is different from tennis because the serve functions differently in these sports. In table tennis, when playing singles you can serve to either side — left or right — on each point, which is not true in tennis. So if your goal is to hit it where the returner isn’t, singles provides a big advantage. And in neither sport is the server’s partner as likely to smash away an errant return as in tennis. (Table tennis doubles rules also restrict where the server can hit it.)In volleyball, a point when you serve is considered one on which you’re playing defense. That’s especially true for men. Most serves don’t win the point outright, and when they don’t, the receiving team has three hits to control the ball, set it and smash it, and the sport has developed highly complex plays designed to win the point outright with its first possession. But as tough as it looks for servers in volleyball, the numbers in the table slightly understate the challenge a typical volleyball server faces. That’s because the numbers are aggregated over all teams. But in volleyball, the team that won the prior point gets to serve. So the stronger teams get to serve more, which weighs their serving success more heavily than that of weaker teams. Some of what looks like the limited serving success for volleyball players in the table is really strong teams’ overcoming the serving liability to withstand their opponents’ attacks and get the point.2In badminton — for which we have the data, unlike volleyball — averaging across teams instead of points, which gives you a fairer sense of the typical server’s chance of winning the point, lowers servers’ success rates by about two percentage points.The stats are pretty consistent at other levels of the game. Todd Dagenais, coach of the University of Central Florida women’s volleyball team, said teams in his team’s league, the American Athletic Conference, win on the serve between 38 percent and 45 percent of the time. Alan Reifman, a Texas Tech University professor who is also a volleyball analyst, said 40 percent is typical in the women’s college game. Top men’s World League Volleyball teams score on 31 percent to 38 percent of their serves.In a way, volleyball servers have it easy. They’re not expected to win the point anyway, so success is a pleasant surprise. And they get to take more risks. When you’re probably going to lose the point if the ball goes in anyway, you lose less by missing, so why not aim a little closer to the top of the net or toward the sidelines or back line? In beach volleyball at the Olympics, men have lost the point by missing their serve about 13 percent of the time, and women 11 percent, according to data provided by Giuseppe Vinci, founder of the analysis site VolleyMetrics. That compares to 3 percent to 4 percent in tennis and less than 1 percent in some of the badminton events. Not all the sports record aces, and some define them differently than others, but tennis players also hit more of those than some of their peers — in part because they get two chances to serve, so they can take big risks on the first serve.“A ‘just keep it in, let them make mistakes’ philosophy used to be more common,” Joe Trinsey, assistant coach of the U.S. women’s indoor team, said by email. “But with the speed and power of the attacks (as well as the tactical complexity and deception of the offenses) increasing each generation, it is becoming more common to see coaches pushing their teams to attack more from the service line, even if it means more errors.” read more

Opinion Former Buckeyes will be on display in Super Bowl 50

Credit: Courtesy of TNSOhio State’s football season might be over, but a handful of Buckeyes are preparing for the biggest sporting event of the year. On Sunday, five former standouts from OSU will be competing in Super Bowl 50 between the Carolina Panthers and the Denver Broncos.Wide receivers Corey “Philly” Brown and Ted Ginn Jr., safety Kurt Coleman and left guard Andrew Norwell are suiting up for the Panthers, while cornerback Bradley Roby plays for the Broncos. All are key contributors and could very well be deciding factors in Sunday’s highly anticipated showdown.Looking at the former Buckeyes, each have played integral roles in helping their conference champion squads to this point. The Panthers had big questions surrounding their offense before the season began, but those have since been answered in large part thanks to Brown, Ginn and Norwell.Former Buckeye and Broncos cornerback Bradley Roby (29) sprints out of the end zone after an interception in the AFC Championship Game on Jan. 24 in Denver. Credit: Courtesy of TNSIn an offensive system that likes to spread the ball around, Brown and Ginn served as two much-needed playmakers, combining for 75 receptions, 1,186 yards and 14 touchdowns. In the NFC Championship Game, Brown reeled in a career-long 86-yard touchdown catch, while the nine-year veteran Ginn provided an electrifying 22-yard run in Carolina’s 49-15 rout of the Arizona Cardinals. Both Buckeye wideouts will try to take the top off the Broncos defense, something the former OSU receivers have been able to do throughout the season.Down in the trenches, Norwell helps anchor an offensive line that was supposed to be the weakest link on the team. Thanks in part to the much-improved second-year guard, the Panthers have one of the strongest rushing attacks in the league, and it has kept quarterback Cam Newton upright (hit only 61 times, third-fewest in the NFL) and “dabbing” on the way to what should be his first MVP award.Former Buckeye and Carolina Panthers receiver Corey Brown (10) goes up for a catch during the NFC Championship Game against Arizona on Jan. 3 in Charlotte, North Carolina. Credit: Courtesy of TNSColeman, in his first year with the Panthers, was signed in the offseason with the goal of reigniting a career that many thought was nearing its end after just six years. Not only did he silence that talk, but the Clayton, Ohio, native led the team with seven interceptions and recorded two more picks in Carolina’s victory over Arizona.Joining Coleman in the defensive ranks is Roby, who was Brown’s college roommate. Roby has been fantastic for the Broncos since arriving in 2014, collecting three interceptions with 23 passes defended, including a game-winning scoop-and-score in Week 2 this season against the Kansas City Chiefs. Although he’s officially Denver’s third cornerback, he is rarely ever not on the field. Roby will likely line up across from Brown at times on Sunday, a matchup that’s worth keeping an eye on.From the look of it, this Super Bowl has all the makings of a classic, especially in the eyes of the OSU faithful. It’s a rare occurrence to have five starters from one school competing for a championship, and it’s not something that should be taken for granted.The Scarlet and Gray’s football season might have ended back on Jan. 1, but their season comes back to life on Sunday beginning at 6:30 p.m. thanks to their former star players. read more

Utility to Build Solar Farm at Navy Sites on Guam

first_imgThe Navy is planning to lease almost 200 acres to the Guam Power Authority to install photovoltaic solar panels in eight locations capable of generating up to 43.8 megawatts of power.Officials are seeking public comment on the project after issuing a draft environmental assessment (EA) Friday.Four of the arrays would be located at Navy Base Guam in the southern half of the island, and four arrays would be located at sites in northern Guam, reported Stars and Stripes.“We approached the Navy several years ago with a request to possibly utilize their properties, and today we believe we’ve reached a major milestone in our process with the publishing of this draft EA for public comments,” said John Benavente, general manager of the Guam Power Authority.Commander, Joint Region Marianas is proposing to provide a 37-year lease of the land to the power authority. The energy generated by the solar arrays would feed into the utility’s electric grid for public and military use.“These projects will bolster energy security and lessen Guam’s dependency on imported fuel,” Capt. Glenn Shephard, commanding officer of Naval Facilities Engineering Command Marianas, said in a written statement. Dan Cohen AUTHORlast_img read more

Subpicosecond photonefficient imaging using singlephoton sensors

first_img Active imaging has broad applications across disciplines that range from autonomous driving to microscopic imaging of biological samples. Key requirements for these applications include high accuracy with timing, fast acquisition rates, dynamic operating ranges and high detection sensitivity to image objects hidden from a camera’s view. Remote sensing and automated applications demand acquisition ranges from <1 meter to the kilometer scale. Non-line-of-sight imaging relies on obtaining encoded information via the few returning photons of multiply scattered indirect light, in addition to the directly reflected light. To enable these applications, ultra-sensitive detectors were developed to record individual photons returning from a pulsed source of illumination. Single -photon avalanche diodes (SPADs) are one of the most sensitive time-resolved detector technologies that can be produced using the complementary metal-oxide-semiconductor (CMOS) manufacturing process. The SPADs were rapidly established as a core detector technology for 3D imaging.In its principle-of-function, SPADs are reverse-biased photodiodes that operate in Geiger mode, i.e. above their breakdown voltage. When photons are incident on the active surface of a SPAD, a time stamped electron avalanche can be triggered. Repeated time stamping of photons returning from a synchronously pulsed illumination source that typically operate at MHz rates can accumulate a histogram of photon counts in time. The resulting histogram documents the approximate intensity of the returning light pulse to recover and characterize the distance, reflectance and 3D geometry of an object hidden from view. The performance of the proposed method was assessed on two scenes with highly varying reflectance and depth profiles, which included the Statue of David and a Bas-relief scene. Both instances contained objects with complex geometries and varying reflectance properties including specular behavior for the "Statue of David" and Lambertian reflectance with spatially varying albedo in the 'Bas-relief" scene. For both scenes the scientists captured a ground truth reference measurement (information provided by empirical evidence) with a 5% neutral density filter, which eliminated pileup distortions by damping the source intensity. The hardware of the system contained a time-resolved sensor, pulsed laser, illumination and collection optics. The setup also had a set of scanning mirrors to achieve a raster scan illumination pattern. The timing of photon arrivals was captured with a PicoHarp 300 time-correlated single photon counting module. The illumination source was a 450 nm or 670 nm picosecond laser (generating full width at half maximum FWHM, pulse widths of 90 ps and 50 ps). The collection optics consisted of a 75 m objective lens, 30 mm relay lens and a microscope objective, designed to extend the field of view of the SPAD across the area scanned by the source of illumination. The experimental measurements served as input for the proposed method and were acquired without any filters in the optical path. Depth and albedo reconstructions along with corresponding error maps were obtained during the study. The results verified that the proposed method achieved high-quality reconstructions unaffected by scene-dependent pileup or shot noise (electronic noise associated with the particle nature of light). The results were compared to conventional methods, such as the log-matched filter-estimate and Coates' pileup correction method that did not as effectively suppress pileup and suffered from scene-dependent depth precision. In contrast, the method introduced by Heide et al. achieved sub-picosecond accuracy. Experimental hardware for 3D imaging.

(a) A collimated, pulsed laser illuminates the scene at a single point. The laser is laterally scanned using a 2-axis mirror galvanometer. Timing and control electronics time-stamp each detected photon arrival relative to the last emitted pulse and accumulate these events in a histogram of spatio-temporal photon counts (b). This histogram is processed to estimate both reflectivity and depth information (c). Two points are highlighted, one corresponding to high-flux (d) and the other to low-flux (e) measurements. Whereas the latter are noisy, high-flux measurements suffer from pileup distortion which introduce a significant bias for the depth estimation of conventional algorithms. The proposed estimation method accurately models both of these scenarios, allowing for reflectance information and travel time to be estimated with sub-picosecond accuracy from severely distorted measurements.

Credit: Scientific Reports, Doi: 10.1038/s41598-018-35212-x © 2018 Science X Network Depending on the expected application, SPADs can operate in free running mode (that allows all photon events to be simultaneously detected at all arrival times) or gated mode (where only photons in a specific time window between pulses are detected). All applications are subject to a fundamental phenomenon known as pileup distortion that severely limits accuracy. Pileup can inherently limit the working principle of the SPAD detector. For example, after each triggered electron avalanche, the detector requires quenching prior to detecting further photon arrival events. During this 'dead time' (ten to hundreds of nanoseconds), the detector is inactive. This may result in the earlier photons of a single laser pulse triggering an avalanche, while later pulses are likely ignored in the dead time; creating inaccurate skewed measurements known as pileup. The phenomenon can be avoided by operating active imaging systems in a low-flux regime, as seen with state-of-the-art techniques used for first-photon imaging before. However, conditions vary for 3D imaging applications in robotics, biological imaging or automotive sensing as they operate in environments where objects reflecting both high and low numbers of photons are essential for decision making. The large variance in acquired photon counts that results from diverse depths or the varying reflectivity of different objects is crucial for 3D imaging. In this work, Heide et al. introduced a new algorithm of estimation that overcame existing limitations of active 3D imaging systems using free running SPADs. The proposed method improved the accuracy of the existing depth and albedo estimation, across a wide range from low-flux to high-flux measurements. The scientists introduced a probabilistic image formation model that included pileup, with efficient inverse methods derived for depth and albedo estimations. The reconstruction framework jointly estimated all unknown parameters to overcome algorithmic limitations that previously restricted the timing precision. The proposed method allowed highly accurate and fast 3D imaging to open new operating regimes of photon-efficient 3D imaging applicable in conditions with dramatically varying photon counts. center_img The code and data used by Heide et al. to generate the findings of the study will be available on GitHub. In total, the proposed probabilistic image formation model and corresponding inverse methods attained sub-picosecond accuracy for active 3D imaging, despite the laser pulse widths being larger than 50 ps. The novel method achieved high precision across a dynamic range from low-flux to high-flux measurements compared to traditional techniques. In the future, the proposed method can facilitate long-range acquisition by multiplexing multiple pileup affected responses. The proposed innovation paves the way for fast and precise photon-efficient 3D imaging systems, where widely varying photon counts are observed in practice. Applications can range across broad disciplines to include 3D mapping and navigation, art reconstruction and conservation, autonomous driving, vision for robots and machines, geographic information, industrial and microscopic imaging. Single-photon avalanche diodes (SPADs) are promising detector technologies that may be used to achieve active 3D imaging systems with fast acquisition, high timing accuracy and high detection sensitivity. Such systems have broad applications in the domains of biological imaging, remote sensing and robotics. However, the detectors face technical impairments known as pileup that cause measurement distortions to limit their precision. In a recent study, conducted at the Stanford University Department of Electrical Engineering, scientists Felix Heide and co-workers developed a probabilistic image formation model that could accurately model pileup. Using the proposed model, the scientists devised inverse methods to efficiently and robustly estimate the scene depth and reflectance from recorded photon counts. With the algorithm, they were able to demonstrate improvements to the accuracy of timing, compared to existing techniques. More importantly, the model allowed accuracy at the sub-picosecond in photon-efficient 3D imaging for the first time in practical scenarios, whereas previously only widely-varying photon counts were observed. The results are now published in Scientific Reports. Journal information: Scientific Reports More information: 1.

Hakim turns saviour for 15 illfated mishap victims

first_imgKolkata: The humanitarian face of state Urban Development and Municipal Affairs minister Firhad Hakim came to the forefront in the wee hours on Sunday morning, when he came to the rescue of around 15 people who met with an accident at Dum Dum Park area on VIP Road.According to sources, at around 3.10 am when the minister was returning from Netaji Subhas Chandra Bose International Airport after welcoming the pilgrims who had returned from Haj, he came across a matador that had toppled onto its side, with a number of people found trapped inside the vehicle. Also Read – Rain batters Kolkata, cripples normal lifeThe minister immediately got down from his car and drew the attention of the patrolling police. He, along with his guards and the policemen joined hands to rescue the trapped and injured persons. Under the minister’s instructions and supervision, prompt arrangements were made to transport the injured persons to a nearby hospital as soon as possible. A police vehicle and three app cabs that were found on the road at the time were used for carrying the injured. “The minister supervised the entire operation and left only after all the injured persons reached the hospital,” said a close aide of the minister, who was accompanying him. According to police sources, the ill-fated matador was going towards Chakla, the birthplace of Baba Lokenath. Chakla Dham is a well-known pilgrimage site located near Basirhat in North 24-Parganas. “Bengal is known for its unity in diversity and upholding of communal harmony. It is my duty as a public representative to stand by everyone if they are in crisis,” the minister said.last_img read more

Baker Mayfield and Colin square off in person

first_imgCavs need to make a big move on draft night to try and keep LeBronThe Lakers are the odds on favorites to land LeBron James, but if the Cavs are going to have any shot to convince James into staying Colin thinks they need to make a big move on draft night. He thinks they should package the eighth pick and Kevin Love and try to make a splash move that will make LeBron re-consider. Trae Young is definitely not the “next” Steph CurryThe NBA Draft is tonight and one popular take by media and fans is the idea that Oklahoma sharpshooting guard Trae Young is the “next” Steph Curry. Young has some range, but Colin thinks the comparisons are ridiculous because Curry has literally revolutionized the modern NBA and already won three titles.The reality is there is no “next” Curry, like there isn’t a “next” LeBron. Young definitely isn’t it and could be a bust because he doesn’t play defense.

Trump leads Republicans but Democrats thump him new poll shows

first_imgWASHINGTON, D.C. – Bombastic U.S. billionaire Donald Trump handily leads all fellow Republicans in the 2016 presidential race, but Hillary Clinton and other Democrats trump him in head-to-head match-ups, a poll said Thursday.Trump plunged into the crowded Republican nomination battle last month, and has since uttered insults about Mexican immigrants and caustic jabs at rivals that has kept campaign media attention focused squarely on the trash-talking real estate mogul.He now leads the 17-candidate Republican field with 20 percent support.Following him were conservative Wisconsin Governor Scott Walker with 13 percent and former Florida governor Jeb Bush, the son and brother of two presidents, with 10 percent, according to a national survey by Quinnipiac University.No other Republican topped six percent.Trump’s negatives are sky-high, however. He led the “no way” list, with 30 percent of Republicans saying they definitely would not support him.“They love him and they hate him,” said Quinnipiac University Poll assistant director Tim Malloy.“He is on fire in his own party,” but Clinton would “crush him” and other Democrats including Vice President Joe Biden, who is not even a candidate, would prevail against Trump, Malloy told AFP. “So he’s running away with it on one side but if today were election day, Donald Trump would not be president.”Ex-Secretary of State Clinton leads rival Democrats overwhelmingly with 55 percent support among Democratic voters, according to the poll. Independent Senator Bernie Sanders is second with 17 percent, while Biden earns 13 percent. All three lead Trump in hypothetical matchups, with Clinton the furthest ahead at 48-36 percent, according to Quinnipiac.Clinton matchups against other Republicans are toss-ups. She nips Walker 44-43, but trails Bush 41-42, poll results showed.Quinnipiac said its July 23-28 poll of 1,644 registered voters has a margin of error of 2.4 percentage points.Trump has made a big splash in two closely-watched states that vote early in the party primary process: New Hampshire and Iowa.An NBC/Marist poll released Sunday had Trump with a seven-point lead in New Hampshire and two points behind the leader in Iowa.A CNN/ORC poll put Trump at the front of the Republican pack with 18 percent, and Bush in second with 15 percent.Trump roiled the presidential race and sent the Republican establishment into convulsions last month when he described some Mexican immigrants as criminals and “rapists.”On Wednesday, he told CNN he would deport millions of undocumented workers if he were president but would let the “good ones” re-enter to live in the country legally.Several Republican Party leaders have spoken out against Trump and his comments, but many ordinary voters frustrated with Washington have expressed appreciation for his blunt talk.Malloy said Trump’s name recognition is a huge factor early in the campaign.“He has an airplane, he has buildings with his name, he has golf courses, he has beauty pageants… Trump is everywhere and has been everywhere for a long time,” Malloy said.“Everybody knows who he is. … That’s a huge asset.” Facebook Comments Related posts:Hillary Clinton promises to be the US’ renewable energy president For Mexicans, the Donald Trump candidacy is getting scarier Donald Trump under fire yet again, this time for sexist and vulgar Clinton gibes Trump shrugs off jihadist video that uses his Muslim ban remarkslast_img read more
