There are those who speculate that the New Yorker PTB do, indeed, want to sabotage Obama's campaign. So far he is still the "presumptive nominee" of the Democratic Party, and if his campaign were to pretty much crash and burn -- i.e., if it became clear that he had little chance of overcoming the prejudices against him and the smears of the Rove machine -- before the Denver convention, there would be a roll call on the floor of the convention and either Barack would withdraw (under pressure from the party bigwigs) or Hillary would beat him outright. She, of course, has pretty much kept her powder dry for such an eventuality, and the superdelegates definitely can swing the decision either way, since they are not "committed" in the same way that regular delegates are.

I can't say I'm buying into this theory wholesale, but I don't believe it's beyond the realm of possibility either.
