Florida will award three delegates to the winner in each of its twenty-something Congressional districts. Florida will then award another group of delegates, again about twenty-something if I remember correctly, to the overall winner of the state. If I'm getting the numbers right, the winner of Florida may pick up just a few more delegates than the candidate who finishes second. Mr. Thompson has the best chance of winning large numbers of districts plus the overall state to make Florida a huge win. That win would make him hard to beat. However, a win for Mr. Romney after winning two caucuses and a primary will look very good. The "winner-take-all" rules in the New York primary will keep Rudy Giuliani in the race until February 5, but a loss in Florida would hurt him badly.

It's the 21st Century. Things have radically changed.
Thompson could not have accomplished this feat in the 70s.
