Mike Huckabee, the former governor of Arkansas and a favorite among Evangelicals, has not won a race since the Iowa caucuses. He trails in funding and organization, but in a state where about 25 percent of GOP voters are evangelical, he cannot be counted out completely.
Then there's Rudolph Giuliani. The former New York mayor spent most of 2007 atop national polls, only to see that lead fade as he gave up on the early contests and put all his focus on Florida, the nation's fourth-largest state and home to many transplanted New Yorkers. So far, at least part of the gamble has paid off: There is no clear front-runner among Republicans, and the field is crowded; add to the mix libertarian favorite Rep. Ron Paul and former Sen. Fred Thompson of Tennessee. So even a modest plurality of votes could win Florida. And win he must, analysts say.
