The Santorum campaign made a last-minute effort to find votes in Michigan with this robocall, which encourages Michigan Democrats to vote for Rick Santorum (and against Mitt Romney) in today’s primary. Michigan’s open primary system means there’s no party registration requirement and voters can vote in whichever party’s primary they choose.

“Romney supported the bailouts for his Wall Street billionaire buddies but opposed the auto bailouts,” says the voice on the pro-Santorum robocall. “That was a slap in the face to every Michigan worker, and we’re not going to let Romney get away with it.” Santorum opposed the bailouts of both the auto industry and Wall Street banks, a fact the ad does not mention.
