North Haven, CT…Eleven months before the 2016 presidential election, Donald Trump is the undisputed leader in the Republican field, as Dr. Ben Carson, in a virtual tie with Trump four weeks ago, drops to third place, according to a Quinnipiac University National poll released today. On the Democratic side, former Secretary of State Hillary Clinton widens her lead over Sen. Bernie Sanders of Vermont to 60 – 30 percent, compared to 53 – 35 percent in a November 4 survey by the independent Quinnipiac (KWIN-uh-pe-ack) University Poll. Former Maryland Gov. Martin O’Malley has 2 percent, with 6 percent undecided.

Trump gets 27 percent of Republican voters today, with 17 percent for Sen. Marco Rubio of Florida, 16 percent each for Carson and Sen. Ted Cruz of Texas and 5 percent for former Florida Gov. Jeb Bush. No other candidate tops 3 percent, with 8 percent undecided.

Last month, Trump had 24 percent, with 23 percent for Carson.

Among Republicans, 26 percent of voters say they “would definitely not support” Trump, with 21 percent who would not back Bush.

“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,” said Tim Malloy, assistant director of the Quinnipiac University Poll.

“Dr. Ben Carson, moving to center stage just one month ago, now needs some CPR. The Doctor sinks. The Donald soars. The GOP, 11 months from the election, has to be thinking, ‘This could be the guy.’

“Secretary Hillary Clinton and Sen. Bernie Sanders have to be hoping Trump is the GOP’s guy.”

American voters shift to Clinton as the Democrat gains ground against Republicans:

47 – 41 percent over Trump, compared to 46 – 43 percent November 4;
Clinton at 45 percent to Rubio’s 44 percent, compared to a 46 – 41 percent Rubio lead last month;
Clinton tops Cruz 47 – 42 percent, compared to Cruz at 46 percent to Clinton’s 43 percent last month;
Clinton at 46 percent to Carson’s 43 percent compared to Carson’s 50 – 40 percent lead last month.

Topping Trump 49 – 41 percent;
Getting 44 percent to Rubio’s 43 percent;
Beating Cruz 49 – 39 percent;
Leading Carson 47 – 41 percent.
