I almost posted earlier, but it wasn't clear. And now it is.
I thought that Obama would want South Dakota's delegates to put him over the edge, just in case the race there didn't go his way -- as the only recent poll has strongly suggested it might -- and that way, he denies the Hillary story it would provide.

I cancelled the post about twenty minutes ago, and at 9, the anchors broke into John McCain's "speech" to announce that finally Obama has won the nomination.

Yours, finally,
