Donald Trump took a major hit in Iowa, where he wasn't "the winner" as he predicted. He needs a comeback, and insults are flying. Ted Cruz scored an upset but, in New England, he's on shakier ground, while Marco Rubio is trying to make third place look like a victory. Bush, Christie and Kasich aren't giving up, but a poor showing on Tuesday could put any one of their campaigns on life support. New Hampshire will play a major role in shaping what could be a long nomination contest to come.
