(CNN) - Florida Rep. Kendrick Meek's latest ad requires no fact check.
That's because it's composed of seven video clips of Gov. Charlie Crist touting his conservative credentials and aligning himself with George W. Bush and Sarah Palin.
The Democratic gubernatorial nominee's ad features no narrator and no graphics. The words "How conservative is Charlie Crist?" dissolve on screen at the top of the ad, followed by clips of Crist speaking in television interviews, press conferences and debates.
Crist, who has held elected office as a Republican in Florida for nearly two decades, is now trying to establish himself as an independent candidate capable of siding with either party, depending on the issue. Meek is trying to chip away at Crist's Democratic and independent support by painting him as an independent in name only.
In one sound bite, Crist calls himself "a pro-life, pro-gun, anti-tax Republican." In another, he says, "I think it's important for people to understand who the true conservative is in this race - and it's Charlie Crist."
The ad, which is airing statewide, was paid for by Meek's campaign and the Florida Democratic Party.
Crist's campaign did not respond to CNN's request for comment.
A Mason-Dixon poll of Florida likely voters released Saturday showed Meek trailing Crist by five points, 28 to 23 percent. Both candidates, however, trailed GOP nominee Marco Rubio, who had 40 percent of likely voters' support. Meek had picked up five points while Crist dropped five since Mason-Dixon's August survey.
A new CNN/Time/Opinion Research Corporation poll of likely Florida voters is set to be released Wednesday.
