In a boon for the frontrunners, a national Quinnipiac Poll released Wednesday shows former Secretary of State Hillary Clinton and billionaire businessman Donald Trump widening their leads in the Democratic and Republican presidential primaries.

Trump had been nearly tied with neurosurgeon Ben Carson in an early November poll, but has now opened up an 11-point lead with 27 percent of the vote. On the Democratic side, Clinton doubled up on Vermont Sen. Bernie Sanders, earning 60 percent to his 30 percent in a hypothetical primary matchup.

Voters ranked the economy and jobs as as their top issue. Trump and Clinton led their fields in that area, but got low marks for honesty and trustworthiness. Sixty percent of voters across both parties said Clinton was not honest and 59 percent said the same of Trump.

In a general election, both Clinton and Sanders come out ahead of all of the top GOP candidates, with the largest projected margins of victory against Trump.

"Secretary Hillary Clinton and Sen. Bernie Sanders have to be hoping Trump is the GOP’s guy," said Tim Malloy, assistant director of the Hamden-based university's poll.

While Trump has the most support, 26 percent of Republicans polled said they "would definitely not support" the candidate. Florida Sen. Marco Rubio moved into second on the GOP side at 17 percent, with Carson at 16.

Trump has continued to make headlines for his controversial comments, including in the past week when he claimed that "thousands" of Muslims in New Jersey were celebrating after 9/11 and allegedly mocked a reporter with a disability.

Those two incidents, which happened around the time the poll was conducted, seemed to have no effect on his support.

"It doesn’t seem to matter what he says or who he offends, whether the facts are contested or the 'political correctness' is challenged, Donald Trump seems to be wearing Kevlar," Malloy said.

Pollsters interviewed 672 Republicans and 573 Democrats in the last week of November. The poll has a margin of error of 2.6 percentage points.
