Running mate for HIllary?
Plausible. But, you never can tell. This kid may catch lightning in a bottle. Hill's negatives are legion. The power may decide to throw her under the bus.
There will not be an Clinton - Obama ticket because the Dems will be scared to put a woman and black man on the ticket at the same time. If Clinton, Obama or Richardson gets the nomination they will have to pick some white guy (Bayh) as their VP.
Obama and Bill will hit the campaign trail together after the convention and draw crowds like the U2 and the Rolling Stones.
