While I agree that Hillary would be the obvious choice to bolster Obama’s chances, I can’t see Obama trusting the Clintons enough to take the chance. With Hillary one heartbeat away from the presidency, Bamster might feel a little nervous. Plus Sweet Moochelle would never stand for it.
This is "business".
Besides, the Clintons have been pretty much "scooped". They got nuthin' (ceptin' a few WH place settings.)
