Rick Santorum Ad Attacks Mitt Romney Without Spoken Words

Rick Santorum's presidential campaign released a new television ad on Thursday that features no spoken words, save the former senator approving the ad's message.

The spot, which will air in Michigan, is nothing more than a compilation of past Mitt Romney quotes and positions, which flash on the screen in white text against a black background. Despite the lack of sound, it's a remarkably effective attack on the former Massachusetts governor.

"Since Mitt Romney refuses to talk about his own liberal record - we figured we'd show people what Mitt Romney says about Mitt Romney," Santorum spokesman Hogan Gidley said in a statement. "We wanted to give Governor Romney's long-held positions and statements an opportunity to be heard."

UPDATE: 12:30 p.m. -- Ryan Williams, a spokesman for Romney, emailed over the following response to the Santorum campaign ad.

“Senator Santorum’s dishonest attack ad is a desperate attempt to distract from his long career in Washington and his decision to repeatedly increase the debt ceiling and his own pay. He will do and say anything to avoid a discussion about his votes for wasteful earmarks and his enthusiastic support of Arlen Specter, the liberal senator who cast the deciding vote for ObamaCare. If business as usual in Washington is the problem, Rick Santorum can’t be part of the solution.”
