I agree that Delegates from Michigan et al. will be seated at the Convention. Their make-up will depend upon negotiations, but to leave them out moves votes to the Republicans. Also unconstitutional? I'll plead ignorance on that, but would like to hear what the legalities are. It also should be pointed out that the decision was taken by the Party executive and, I have seen in reviews, must be confirmed at the party convention.

Obama has cultivated the technique of the old time political orator (with, I agree, a nod toward Martin Luther King - the latter he turns on and off depending on his audience).
