The latest Rasmussen Reports telephone survey in Florida shows former Massachusetts Governor Mitt Romney earning 33% of the vote while Arizona Senator John McCain attracts 27%.The poll was conducted Saturday afternoon before Florida Governor Charlie Crist announced his endorsement of McCain and the race is fluid enough that both men have a realistic chance of winning on Tuesday. Rasmussen Markets data showed that expectations for a McCain victory rose following the Crist announcement.

Among voters who consider the economy the most important issue, Romney has a very narrow edge over McCain, 37% to 33%. Among those who name either the War in Iraq or National Security issues as most important, the candidates are tied at 31%. Immigration is seen as the top issue by just 12% of Florida’s Likely Republican Primary Voters, but they overwhelmingly favor Romney over McCain by a 63% to 7% margin. Huckabee picks up 16% of those who consider immigration the top priority.

Earlier this week, just before the Florida debate, Romney led by four percentage points. A poll conducted last Sunday found Romney leading by five.

As Florida voters seek to decide between the two frontrunners, support for other candidates is fading. Rudy Giuliani is a distant third at 18%, Mike Huckabee 12%, some other candidate, 5%, and Ron Paul 2%.

Three percent (3%) of Florida’s Likely Voters have yet to make up their mind. Another 21% say they might still change their mind. That figure includes 8% who say there’s a good chance they could change their mind before voting.

Fifteen percent (15%) of Giuliani’s supporters say there’s a good chance they could change their mind, a higher percentage than for any other candidate. That’s potentially good news for John McCain.

Eighty-five percent (85%) of Huckcabee’s supporters are either certain they will vote for him or have already voted. Eighty percent (80%) of Romney’s supporters are that “certain” along with 79% of Giuliani voters and 72% of those who support McCain.

Romney is now seen as the most electable Republican candidate—76% believe he would be at least somewhat likely to win the White House if nominated. Sixty-eight percent (68%) say the same about McCain. Earlier in the week, both men were viewed as at least somewhat likely to win by 69%.

Nationally, in the Rasmussen Reports daily Presidential Tracking Poll, McCain and Romney have begun to pull away from the rest of the field. The economy is seen as the top voting issue for all voters nationwide.

Looking ahead on the Primary Calendar, Huckabee leads in Georgia, Huckabee and McCain are essentially tied in both Missouri and lead in Alabama. McCain leads in New York, McCain and Giuliani are close in New Jersey, while McCain and Romney are close in California.

Rasmussen Markets data suggests that McCain has a % chance of winning in Florida while Romney is given a % chance. Immediately following his victory in South Carolina, McCain was given a 70% chance of winning Florida. Expectations for McCain declined for several days and, following the Thursday night debate, Romney became the favorite to win. But, McCain got a boost following the Crist endorsement on Saturday night. According to the markets, Giuliani is a distant third with a % chance of victory.
