Nate Silver reckons there is a 97% chance that Mitt Romney will take out the Florida primary tonight:
The shift away from Newt Gingrich in the Florida polls has been as significant as the one toward him in South Carolina.

But the news has gotten worse for him almost every day, and he trails Mitt Romney by nearly 15 points in the final FiveThirtyEight forecast of the Florida primary.
