At that point, Obama really should just push her to the side.
If the superdelegates and major party leaders don't line up behind Obama after a win in Indiana then they're complete idiots. They can't let Clinton keep campaigning through West Virginia and Kentucky.
Actually, maybe they should. As long as her name is on the ballot in those states, she's going to win them. We don't want Obama losing to a non-candidate.
Look how much it hurt McCain to lose Kansas and Louisiana against a dead man walking.
Not quite the same, Huckabee was still a candidate at least.
