Santorum: Romney, Huntsman have 'holes in their record'

Former Sen. Rick Santorum (R-Pa.) went on the attack Wednesday, saying that former Massachusetts Gov. Mitt Romney (R) and former Ambassador to China Jon Huntsman (R) suffer from "holes in their record."

Santorum, speaking in Iowa, chastised Romney and Huntsman for avoiding the Hawkeye State, suggesting their records make it more difficult for them in the Republican contest there.

"The bottom line is my values line up with the people of Iowa, and they line up with the Republican Party," Santorum told WHO television. "And I think it shows holes in their record on a variety of issues that they can't go out and compete everywhere."

Santorum's been more openly critical of Romney and Huntsman than most other members of the Republican presidential field. The pair are expected to focus more on the New Hampshire primary and subsequent contests than the Iowa caucuses, where Santorum hopes to make a play and where his brand of social conservatism may play well.

"I think when you don't have a record that is solid across the board or has been somewhat all over the place, then you have to pick and choose where you can do well. I don't think that's our strongest candidate when it's all said and done," Santorum said.
