If there is a clear Democratic winner, the Democrats will almost certainly count all of the Florida and Michigan delegates. But if not, and if these delegates make a difference, then they might well not count them - why? Because if these delegates make Clinton the nominee over Obama, the Democratic Party is going to alienate a whole lot of blacks who will feel that they were cheated. Same is true if the superdelegates make the difference; that is, if Obama wins the delegates in the "officially counted" states but loses once the superdelegates are counted.
I haven't yet heard anyone bring up the racial angle to this, but it seems clear as day to me.
That is all.
