DAVID CORN: Well, you know, he's not saying anything new taking this position. To me the big question, as he gets closer to running for president, which clearly he wants to do, will he get louder and more vocal on this non-interventionism or this intervention skepticism that he's been pushing because when he does that he is setting up a bloody civil war inside the Republican party... You know John McCain's head will explode, Bill Kristol, if he gets close to getting the nomination.
