Republican Attorney General Bill McCollum has retaken the lead from former insurance industry executive Rick Scott in the battle for the GOP nomination for governor. McCollum holds a 44 to 35 percent lead over Scott, who held an 11-point lead in the same poll just three weeks ago.

Democratic Rep. Kendrick Meek has also regained the lead in the Democratic primary over rival Jeff Greene in the Sunshine State's Senate race, holding a 35-28 percent lead. Greene held a 10-point lead in the most recent Quinnipiac poll.

Each race remains extremely fluid however: Almost 20 percent of Republican voters are still undecided and 32 percent of the respondents who named a candidate said they could change their mind.

On the Democratic side, 29 percent are undecided and 39 percent of voters could change their mind.

"Although this is clearly the year of the outsider, the reverse of that may be in the offing in Florida," Quinnipiac University Polling Institute assistant director Peter A. Brown said. "But nothing is for certain and the large number of undecideds and voters whose commitment to their candidate is soft makes anything possible."

The Republican results were based on a survey of 807 likely primary voters and carries a sampling error of plus or minus 3.5 percent. The Democratic results were based on a poll of 814 likely primary voters and have a sampling error of plus or minus 3.4 percent. Both polls were conducted August 11-16.

Florida's primaries will be held on August 24.
