Eve of FL GOP Primary, Clear Divisions Among Republicans, But No Clear Frontrunner: 24 Hours till voting ends in the Florida GOP Primary, it is easy to describe who is voting for Mitt Romney and who is voting for John McCain, but difficult to tell which of the two will win the Winner-Take-All Primary, according to SurveyUSA’s 9th tracking poll, conducted exclusively for WFLA-TV Tampa and WKRG-TV Mobile. Romney has 32%, McCain 31% at this hour, effectively tied. Rudolph Giuliani and Mike Huckabee are far back. Romney leads by 17 points among voters focused on the Economy, and leads by 24 points among voters focused on Immigration. McCain leads by 14 points among voters focused on Terrorism and by 22 points among voters focused on Iraq. Romney leads by 16 among Conservatives. McCain leads by 28 among Moderates. Romney leads by 14 in SE FL. McCain leads Romney by 14 in NW FL, where Huckabee, showing twice the strength he shows elsewhere in Florida, is six points behind McCain. Romney and McCain are effectively tied in NE FL and Central FL. Compared to a SurveyUSA poll one week ago, completed after McCain won South Carolina, but before Fred Thompson dropped out, both Romney and McCain are up significantly. But Romney is up slightly more, and may have the slightest additional momentum at the wire.
