Where Things Stand (before Texas & Ohio)

Mark Ambinder at the Atlantic has put together a brief little FAQ about "Existential Realities of the Democratic Race." Here's an excerpt:

Q. Can Hillary Clinton win the nomination?

A. Maybe.

Q. Can you be more specific? Is it mathematically possible for her to win the nomination?
A. Yes.

Q. Is it likely that she will win the nomination?
A. Based on the math alone and a reasonable projection of external events, no.

Q. But you said it's possible.
A. Yes. But lots of things have to break her way. If, say, voting ends and the press discovers that Obama has a secret second family in Idaho and all his superdelegates abandon him; if, for some reason, she wins 75% of the popular vote in the states after Ohio and Texas and half the remaining superdelegates; if, by slow attrition, he closes the delegate gap to about 70 and picks off two thirds of the remaining superdelegates; if the pledged (Obama) delegates concur with the credentials committee and seat the (Clintonian) Florida and Michigan delegations) -- then, yes, it's possible.
