Mitt Romney leads Newt Gingrich by 38 to 29 percent in the Florida Republican primary contest, according to a Quinnipiac University poll released Friday. As in the South Carolina contest, Gingrich is strongest among tea party supporters and white evangelical Christians, while Romney does better among others. Romney more than doubles Gingrich’s support among voters under age 50, while Gingrich ties or leads among older votes.

Texas Rep. Ron Paul and former Pennsylvania senator Rick Santorum score 14 and 12 percent support, respectively, jockeying for third place in the primary on Tuesday. There’s still room for movement, as one in three voters say they might change their mind.

Gingrich surged to a victory in South Carolina on the heels of two well-received debate performances. This week, he has been less dominant in debates, while Romney has performed better.
