Former Pennsylvania Sen. Rick Santorum minced no words today in Iowa against Texas Rep. Ron Paul.

“Ron Paul is disgusting,” Santorum told reporters this morning, according to The Washington Post. He apparently was referring to a series of robocalls he attributes to Paul's campaign that accuse Santorum of supporting abortion rights and opposing gun rights.

Paul has been on the attack for some time and on Monday called Santorum "“very liberal ... He spends too much money. He wasn't leading the charge to slash the budgets and vote against big government.”
