Santorum hits Romney, Perry in radio ad

Rick Santorum's on the radio in Iowa with an ad hitting both Rick Perry and Mitt Romney, the Washington Post's Blake reports. The Santorum campaign is spending about $30,000 on the ad.

Listen to it here.

Script below:

"This is Rick Santorum, and if you've watched the presidential debates, you know we're not shy about disagreeing. Mitt Romney and I disagree on his government-run RomneyCare. I think Rick Perry is dead-wrong about giving , and I thought the Wall Street bailouts were a terrible idea, while Herman Cain strongly supports the bailouts, but we all agree on one thing: Barack Obama has to go, and if there's anything we've learned from his failed presidency, it's that experience matters. That's why I hope you'll visit RickSantorum.com, and learn about how I successfully led the fight to reform welfare, my critical foreign policy experience, having served eight years on the armed services committee, and how I ended partial birth abortions in America."
