(CNN) - Marco Rubio is happy to fight fire with fire.
The Florida Senate candidate will launch a pair of 15-second TV commercials Thursday pushing back at a new attack ad from primary rival Charlie Crist, a Rubio source told CNN.
Crist's new ad claims Rubio isn't as conservative as he portrays himself. Rubio is now responding with two short ads that will bracket Crist's commercial "during the same time slots or programming whenever possible," the source said.
The ads cite a recent Associated Press story that described Crist's attacks during the race as untrue, out of context and "over the top."
But perhaps the most cutting part of Rubio's counterpunch is the payoff.
At the end of both spots, viewers are shown the now-infamous image of Crist and President Obama appearing together at a rally for the stimulus package in Fort Myers last year, as rowdy chants of "Yes We Can!" are heard in the background.
Crist's support for the stimulus, of course, has cost him precious support among conservatives.
