Just days after praising his rival GOP presidential candidate, Newt Gingrich took aim at Rick Santorum’s congressional record and said he would be considered the “junior partner” in a match-up between the two Republican hopefuls. “If you think of us as partners, he would clearly in historical experience have been the junior partner,” Gingrich said Thursday on the campaign trail. “He’s not a bad person, I want to be clear about this, but I don’t know that he has any track record of being able to organize a large-scale campaign.”
