Retired neurosurgeon Ben Carson and real estate mogul Donald Trump are effectively tied for the lead in a national poll released by Quinnipiac University on Wednesday.
Among Republican voters, Trump received 24 percent support and Carson received 23 percent support. Following the two frontrunners, Sen. Marco Rubio (R-FL) got 14 percent of voters and Sen. Ted Cruz (R-TX) got 13 percent of the vote. The rest of the Republican candidates polled in the single digits.
Carson has surged six points since the last Quinnipiac national poll at the end of September. And former Florida Gov. Jeb Bush has slipped six points in the past month.

And 37 percent viewed Trump favorably, while 56 percent viewed him unfavorably. Forty-two percent of registered voters viewed Hillary Clinton favorably, and 52 percent viewed her unfavorably.
