John Mellencamp is asking Republican presidential candidate John McCain to change his playlist. The GOP hopeful has been blaring Mellencamp's 'Our Country' and 'Pink Houses' during campaign stops, but the voice behind those songs is a staunch left-winger. In fact, Mellencamp stumped for Democrat John Edwards before he dropped out of the race.

Mellencamp's publicist wrote the McCain campaign a letter explaining the rocker's liberal political stance and asking, "Are you sure you want to use his music to promote Senator McCain's efforts? Logic says that the facts might prove to be an embarrassment, were they to be circulated widely."

McCain has since stopped playing Mellencamp's tunes along the campaign trail.
