I know it's conventional wisdom that the press likes to anoint through focusing on momentum, but we're in a very different situation this year due to two factors: the internet/blogs, and the change towards proportional delegate apportionment.
Deans has vastly more negative press against him than any other candidate, and yet he's still the frontrunner.
So, what happens if on 2/3, Dean has hardly any first place wins, but a lot of second place wins, while everyone else has regional spikes? It's very possible. I just don't see that the press anointing problem would eat into Dean's broad support in this many states when he's already been beat up on so much. If Dean's second in many states, he could still easily have a large lead in delegates over anyone else, even if he hasn't won any individual states.
I don't think the press will know what to do. :-)
