US Democratic presidential hopefuls Bernie Sanders and Hillary Clinton are still in a dead heat, while Republican frontrunner Donald Trump enjoys a double-digit lead over his rivals as the race to win primary votes tightens, a new poll has found.
The Quinnipiac University poll which was released on Wednesday revealed that Clinton and Sanders are still locked in a virtual tie with 44 percent and 42 percent support respectively.
The survey also hinted at a shrinking gender gap between the two candidates, with women supporting the former first lady over Sanders 47 percent to 41 percent, and men backing the Vermont senator over Clinton 44 percent to 40 percent.
However, 83 percent of the respondents said Clinton has a good chance to succeed President Barack Obama into office this November, while 69 percent said the same of Sanders.
With his strong performances in the Iowa caucuses and New Hampshire primary, Sanders has proven himself as a tough challenge for Clinton in the upcoming Nevada caucuses and South Carolina primary.
On the Republican side, Trump was supported by 39 percent of Republican voters, holding a 20-point lead over Florida Senator Marco Rubio, who ranked second at 19 percent.
Senator Ted Cruz of Texas dropped four points to third place with 18 percent, followed by Ohio Governor John Kasich at 6 percent. Nine percent of the participant said they were still undecided on who they were going to choose.
Trump was perceived as the party’s best chance to win the presidency according to 77 percent of the voters, compared to 61 percent for Rubio and 60 percent for Cruz.
While ending up second to Cruz and barely defeating Rubio in Iowa caucuses, Trump scored a decisive lead in New Hampshire and dictated his superior support among voters.
Republican voters in South Carolina will cast their votes next Sunday, while Democratic voters will vote on February 27.
Trump leading in Nevada
According to a state-wide poll released by CNN/ORC on Wednesday, Trump is far ahead of his opponents in Nevada, where the next caucuses are slated to be held this weekend.
The real estate mogul led the GOP field with 45 percent support, trumping Rubio and Cruz who only managed to grab 19 and 17 percent of votes respectively.
Among Democrats, Clinton led in the state with 48 percent support, followed closely by Sanders at 47 percent.
