FiveThirtyEight's Nate Silver:
[T]here is enough evidence — when you look carefully at the day-to-day [polling] results — to conclude that Mr. Romney has re-emerged as the slight favorite in Florida.... [I]t looks as though Mr. Gingrich’s surge may have reached its apogee over the weekend.
The bad news is that Romney's positive trajectory will likely subtract tonight from his pitiable attempts at predatory snarling. The good news is that Gingrich's negative trajectory will unquestionably add to his predatory snarling.
The Lord taketh away, and the Lord giveth.
