It is highly unlikely that more than three candidates will win any states at all, and one candidate will almost certainly win all of the late states. Unless they start performing significantly better, Richardson and Biden won't even win their home states, which come late in the game. Vilsack has already been shown to be struggling in Iowa, and it would be a miracle if he placed second there. Clinton will probably win a couple of states (especially New York and Arkansas), but she'll drop off the radar in most late states. Which of Edwards and Obama will actually win the nomination is as-yet unclear, but it will almost definitely be one of those two.
My personal prediction
Obama: Red
Edwards: Blue
Clinton: Green
