A new national poll shows nearly every major Republican candidate beating Hillary Clinton in a hypothetical general election -- and shows Ben Carson leading by a resounding 10-point margin. 

The Quinnipiac University Poll was taken after last week's GOP presidential debate. In head-to-head match-ups with leading GOP candidates, Clinton only edges out Donald Trump. But the survey showed Carson, the retired neurosurgeon who has been trading the lead with Trump in GOP primary polls, with a 50-40 percent lead over the Democratic front-runner. 

According to Quinnipiac, Clinton's lead among women "evaporates" when she's pitted against Carson. Women break for him over Clinton, 45-44 percent. Florida Sen. Marco Rubio also beats Clinton, 46-41 percent; Texas Sen. Ted Cruz beats her 46-43 percent; and New Jersey Gov. Chris Christie beats her 46-41 percent. 

Clinton still leads Trump, 46-43 percent.
