A poll of likely voters released by Rasmussen Reports on September 15, 2010 has the Republican candidate, former Florida House Speaker Marco Rubio, maintaining his lead over Gov. Charlie Crist, who is running without party affiliation, and the Democratic candidate, U.S. Rep. Kendrick Meek. A Reuters-Ipsos poll released on the same day shows a similar lead for Mr. Rubio in the Senate race and a race for governor that is essentially tied.

In the Rasmussen poll, 41 percent of voters supported Mr. Rubio, 30 percent supported Gov. Crist, 23 percent favored Rep. Meek, two percent supported some other candidate, and four percent were undecided. These results were almost identical to an August 25 Rasmussen poll and reflect a steady decline for Gov. Crist and steady improvement for both of his opponents during the course of the summer.

The Rasmussen poll of 750 likely voters was conducted on September 14 and has a margin of error of four percentage points.

A poll conducted by Ipsos Public Affairs for Reuters has Mr. Rubio at 40 percent of likely voters, Gov. Crist at 26 percent of likely voters, and Rep. Meek at 21 percent of likely voters, with 13 percent undecided. When the survey is expanded to include all registered voters, Mr. Rubio leads with 32 percent, followed by Gov. Crist at 29 percent, Rep. Meek at 22 percent, and 17 percent undecided.

The same Reuters-Ipsos poll also surveyed the race for governor. Among likely voters, Rick Scott, the Republican candidate, led the Democrat, state Chief Financial Officer Alex Sink, by 47 percent to 45 percent, with eight percent undecided. Among all registered voters, however, Ms. Sink led with 45 percent, followed by Mr. Scott with 41 percent, other candidates with one percent, and 13 percent undecided.

The Reuters-Ipsos poll was conducted on September 10 through September 12. The poll surveyed 600 registered voters, of whom 486 were considered likely voters. The margin of error among registered voters was four percentage points, and the margin of error among likely voters was 4.6 percentage points.
