I may just be an unfrozen caveman lawyer, but the way I see it, it shouldn't be that hard for Obama to drag HRC into her own mudpit without getting himself dirty
The best way to do this is to this is to make the math part of his stump speech. It's not that complex: HRC can't catch him in either delegates or raw votes. I know it, you know it, and the saints know it. Unfortunately, not enough voters know it. He needs to pound the point home that the only way HRC can win is to cut a deal with some superdelegates. Her campaign has said as much just tonight: Her endgame is to get the delegates just close enough that democracy can be subverted.
I would suggest that Obama add the words "sleazy" and "backroom" to his campaign vocabulary, and that he use them often.
