(CNN) - Even though he's not in the 2012 presidential race, Texas Gov. Rick Perry leads the pack of Republican candidates in a survey of likely Florida voters by the American Research Group.
Perry polled at 16 percent among registered Republicans, with Minnesota Rep. Michele Bachmann and former Massachusetts Gov. Mitt Romney tying for second place at 15 percent. Fmr. Alaska Governor Sarah Palin came in third with 15 percent, and businessman and radio commentator Herman Cain was in fourth at 11 percent.
The Texas governor has said he's strongly considering a White House bid and feels "called" to run but has yet to make an official announcement.
While Perry tops the field of likely Republican voters, Bachmann snags the lead among tea party supporters, ahead with 20 percent while Perry had 18 percent. Palin received 16 percent of support, and Cain had 13 percent.
A similar survey from May shows major changes in preference for certain candidates. Bachmann, who didn't officially announce her candidacy until June, was trailing at five percent in May but now has 15 percent of support among likely primary voters. Cain also jumped to the double digits, from four percent to 11 percent.
Others went down in numbers. Romney, who was polling at 26 percent in May, dropped down to 15 percent. Former House Speaker Newt Gingrich had 11 percent but now has three percent.
Both former Minnesota Gov. Tim Pawlenty and former Pennsylvania Sen. Rick Santorum remained flat at one percent.
The American Research Group polled 600 likely 2012 Florida Republican presidential primary voters via telephone in a survey conducted July 18-24, with a sampling error of plus or minus four percentage points.
