Rick Santorum announced Friday that his presidential campaign would be debuting a radio ad in Iowa that knocks each of the top-tier candidates for the Republican nomination and plays up his own experience.

"Mitt Romney and I disagree on his government-run RomneyCare. I think Rick Perry is dead wrong trying to give taxpayer funded in-state college tuition rates to illegal aliens. And I thought the Wall Street bailouts were a terrible idea, while Herman Cain strongly supports the bailouts," Santorum says in the ad.

Santorum goes on to say that all the candidates agree President Obama should be defeated in the coming election.

The campaign is expected to spend around $30,000 on getting the spot up on Iowa airwaves, his first in the state. The former Pennsylvania senator believes the Hawkeye State offers his best chance for a surprise showing, hoping he can mobilize conservative and religious voters.

“The strategy is to go down and talk to the people of Iowa and do town-hall meetings. And I have been to 70 counties of the 99 counties," Santorum told Fox News. "We are not hitting huge crowds but we are hitting the people who are the engine of the Iowa caucuses. And they are talking and have influence in their community."
