Latest polling: Most recent from each polling organization:
Nate Silver gives Romney a 98 percent chance of winning, followed by Gingrich at 2 percent. All other candidates are at 0 percent chance to win according to Silver.
Bottom line: At one point, Florida looked primed to give Gingrich a shot to get back into the race, but times change quickly. It's hard to see how Romney doesn't win at this point and it's hard to see how a victory in Florida doesn't all but seal the nomination for him.
