I should make an official prediction about tonight, right? Well, clearly the universe is conspiring to make this primary last as long as possible. So what's going to happen is that (of course) Clinton will win Indiana and Obama will win North Carolina. But Clinton will win Indiana by a larger margin than Obama wins North Carolina, and Clinton's supporters will note in somber tones that Obama lost the white vote in NC. At the same time, because NC has substantially more delegates than Indiana, Obama will actually make a small gain in net delegates causing his supporters (i.e. me) to become further enraged at Clinton's refusal to admit that she's lost and the press' insistence on indulging the idea that there's real doubt about the ultimate outcome.
Save your eyes. Take breaks.
