Santorum calls Ron Paul 'disgusting' for negative robocalls

Rick Santorum blasted fellow Republican candidate Ron Paul as "disgusting" following a media interview Tuesday morning, blaming the Texas congressman for a series of robocalls insinuating that the former Pennsylvania senator was both pro-choice and against the Second Amendment.

"Ron Paul is disgusting," Santorum said, according to a Fox News producer.

Santorum and Paul have been locked in a three-way tie with Mitt Romney atop the Iowa polls heading into Tuesday's caucuses. 

Paul, whose brand of libertarianism breaks from much of the Republican field, has done little to endear himself to the other candidates throughout the campaign. Last week, Newt Gingrich said that he would not vote for Paul if he became the eventual nominee, and that “the choice of Ron Paul or Barack Obama would be a very bad choice for America.”

“I think it’s very difficult to see how you would engage in dealing with Ron Paul as a nominee,” Gingrich told CNN.
