Where did you get that information? I live in Florida and have never heard anything like that. Hope it isn’t factual. Even so, a good percentage should go to Newt.
I was channel surfing last night, and when I briefly switched from FNC to CNN, I noticed that a poll they showed (I forget what poll it was; and I know nothing of the methodology used) showed Mitt Romney at 44 percent in Florida; Rick Santorum in second place, at (a distant) 19 percent; and Newt Gingrich at 18 percent.
I would expect the race to tighten a bit, in any case; and Newt's resounding victory in South Carolina might especially help.
But many of Florida's primary votes have already been cast, due to absentee voting; and momentum will certainly not be a factor among those votes already cast.
