After months of nonstop campaign coverage, Americans will finally turn to Iowa to see some results. No matter how things turn out, you know who will be in the headlines.

From Politico: How Trump Did It: “I’m going to get in and all the polls are going to go crazy. I’m going to suck all the oxygen out of the room.
