Former House Speaker Marco Rubio (R-Miami) leads Gov. Charlie Crist by 12 percentage points in the Republican primary for the U.S. Senate seat currently held by Sen. George LeMieux, according to a survey of likely Republican voters released on February 1, 2010 by Rasmussen Reports.

Mr. Rubio received the support of 49 percent of respondents, Gov. Crist was supported by 37 percent, three percent indicated support for another candidate, and 11 percent were undecided. The survey also found that 43 percent of likely Republican voters either somewhat disapproved (27 percent) or strongly disapproved (16 percent) of Gov. Crist's performance as governor.

In its broader survey of likely voters, Rasmussen found that both Gov. Crist and Mr. Rubio enjoy strong leads over the presumptive Democratic candidate, U.S. Rep. Kendrick Meek (D-17th Congressional District), with Gov. Crist leading by 48 percent to 33 percent, and Mr. Rubio leading by 49 percent to 32 percent.

The automated telephone survey of 1,000 likely voters, including 449 Republican likely voters, was taken on January 27, 2010. The margin of error for the Republican-only questions is five percentage points and the margin of error for the all-voter questions is three percentage points.
