A new poll released out of Florida has Romney increasing support and within the margin of error of Rudy (meaning, since statistics are all about probability, that the poll, which has a margin of error of 5.3%, could in reality have Romney that much higher and Rudy that much lower, putting them in a tie):

Quinnipiac GOP Florida Primary

Rudy Giuliani 27% (28%)
Fred Thompson 19% (17%)
Mitt Romney 17% (11%)
John McCain 8% (10%)
Mike Huckabee 4% (2%)
Ron Paul 2% (2%)
Sam Brownback 1% (0%)
Tom Tancredo 1% (0%)
Don’t Know 16% (18%)

Survey of 345 registered Republicans was conducted October 1-8. The margin of error is +/- 5.3 percentage points. Results from the poll conducted September 3-9 are in parentheses.
