With Florida having the third largest state delegation and using a winner-take-all formula, a victory here could be major for Romney.

The second-place battle between McCain and Giuliani is, of course, key. If McCain can open up a big gap between himself and Rudy, he can make Super Tuesday into a real two-way fight without splitting his vote.
