After striking out with Rage Against the Machine and Dee Snider, Ryan finally found at least one rock star willing to appear onstage with him: Kid Rock, whose song "Born Free" has been adopted by the Romney campaign as its official anthem. Here is a sample of the pair's rockin' repartee at a Michigan fundraiser yesterday:

KR: I was going to be a little wisenheimer and say, "Which one is running for vice president?" Then they would introduce Paul and I would walk out and say hello.

PR: So one of us is running for vice president, but only one of us was listening to "Bawitdaba" in the motorcade on the way over here.

Take that, Tom Morello.
