Even so, being able to claim a win over Romney, however narrow, would truly make this a David vs Goliath moment.
Iowa is usually never a predictor of who will ultimately win. Santorum will have to show he can win in some other state. Or at least have a strong 2nd showing. At some point, the money dries up, and the establishments starts to get behind one candidate. If Santorum cannot get a win or strong show in SC or FL, then it will probably be Newt vs Mitt until the convention. I don’t see Newt dropping out as long as he has any money. Sounds like Perry may be chucking it in early, which is too bad. He was my candidate. But got stuck with a bad meme due to the early gaffs.
