McCain wins Florida primary

MIAMI, FL McCain tells The Associated Press it's a "very significant boost" and shows he's "the conservative leader who can unite the party."

The Florida victory is worth 57 national convention delegates for McCain and is the largest single prize to date in the race.

Rudy Giuliani was in third place and Republican officials say he will endorse John McCain tomorrow in California, indicating the former New York mayor is getting ready to drop out of the race.

Mike Huckabee has told supporters he'll forge on.
