Nate Silver, Five Thirty Eight:
Polls Suggest Gingrich’s Support May Have Peaked

Polling released within the past 24 hours suggests that Mitt Romney may have stopped and possibly reversed Newt Gingrich’s momentum before the Florida primary on Tuesday.

The FiveThirtyEight forecast model still projects Mr. Gingrich as the slight favorite in Florida, giving him a 2-point lead and a 60 percent chance of victory. However, this lead is diminished considerably from two days ago, when the model saw a potential double-digit win for Mr. Gingrich as polls released immediately after the South Carolina primary had him surging in Florida.
