A Mason-Dixon poll released by the Florida Press Association and Leadership Florida on August 5, 2010 indicates that the primary contests for the Republican nomination for governor and the Democratic nomination for the U.S. Senate are tightening.

In the Republican primary for governor, the Mason-Dixon poll shows businessman Rick Scott leading Attorney General Bill McCollum by 37 percent to 31 percent, with 29 percent undecided. Several polls taken by other pollsters in the month of July showed Mr. Scott leading by as much as 16 percentage points. The Real Clear Politics average of polls taken between July 16 and August 4 shows Mr. Scott leading by 41.6 percent to 29.0 percent.

The Mason-Dixon poll also showed U.S. Rep. Kendrick Meek (D-17th Congressional District) leading real estate investor Jeff Greene by 33 percent to 29 percent in the Democratic primary for the U.S. Senate. A Quinnipiac University poll in late July showed Mr. Greene leading by 10 percentage points, while other polls showed a slight lead for Rep. Meek. The Real Clear Politics average of July and August polls showed the race essentially tied, with Mr. Greene leading Rep. Meek by 29 percent to 28 percent.

The Mason-Dixon poll surveyed 625 likely Democratic primary voters and 625 likely Republican primary voters from August 2 through August 4 and has a margin of error of four percentage points.

On August 3, 2010, Rasmussen Reports released its most recent general election poll, which showed Mr. Scott leading if he is the Republican nominee for governor and Chief Financial Officer Alex Sink, the Democratic candidate, leading if Attorney General McCollum is the Republican nominee.

In a three-way race for governor between Mr. Scott, CFO Sink, and no-party-affiliation candidate Bud Chiles, Mr. Scott wins the support of 35 percent of respondents, Ms. Sink is supported by 31 percent, Mr. Chiles is supported by 16 percent, six percent favor some other candidate, and 12 percent are undecided.

Mr. Chiles apparently takes votes from both the Republican and the Democratic candidate. A June 7 Rasmussen poll, taken before Mr. Chiles entered the race, showed Mr. Scott leading with 45 percent, followed by CFO Sink with 40 percent, three percent for some other candidate, and 12 percent undecided.

In a race between Attorney General McCollum, CFO Sink, and Mr. Chiles, CFO Sink leads with 31 percent, Attorney General McCollum is in second place with 27 percent, Mr. Chiles is in third place with 20 percent, eight percent favor some other candidate, and 13 percent are undecided.

Once again, Mr. Chiles appears to draw votes from both of his opponents. The June 7 Rasmussen poll had Mr. McCollum leading with 40 percent, followed by CFO Sink with 38 percent, eight percent for some other candidate, and 13 percent undecided.

The Rasmussen poll of 750 likely voters was conducted on August 2 and has a margin of error of 4.5 percentage points.
