Republican presidential candidate Ben Carson continues to tumble in the polls, according to the latest Quinnipiac poll, which now has Carson tied for third place.
The poll found that front-runner Donald Trump continues his commanding lead over the field, taking 27 percent of support. Florida Sen. Marco Rubio rose to the second position with 17 percent of support.
Carson sits at third, tied with Texas Sen. Ted Cruz, both taking 16 percent of support. In last month's poll, Carson and Trump were at a virtual tie, at 23 percent and 24 percent respectively, but with the extra scrutiny placed on his lack of foreign policy experience, Carson dropped 7 percentage points in just one month.
Former Florida Gov. Jeb Bush rounded out the top-5, garnering 5 percent. Former Hewlett-Packard CEO Carly Fiorina followed in sixth with 3 percent.
New Jersey Gov. Chris Christie, Ohio Gov. John Kasich and Kentucky Sen. Rand Paul followed Fiorina, each tying with 2 percent. Former Arkansas Gov. Mike Huckabee closed out the top 10 with a single percentage point of support.
Former Pennsylvania Sen. Rick Santorum, South Carolina Sen. Lindsey Graham, former New York Gov. George Pataki and former Virginia Gov. Jim Gilmore did not register any support in the poll.
Still, with two months before the Iowa caucuses, the poll found that the majority of Republican respondents have not made up their mind. When asked, 65 percent said they are open to changing their vote, while 32 percent said they are not. Trump supporters are most adamant about their support for the billionaire businessman, however.
The survey of 672 registered Republican voters was conducted between Nov. 23-30. It had a margin of error of +/- 3.8 percent.
