I would love to see the DEMS fighting to the end and making it impossible for them to win. It is just this fear I have that Hillary would manage to win if she were the nominee and she puts Obama on her ticket.
I don't see her picking him as VP. There'd be too much temptation by the teeming hordes of Obama supporters to bump her off. (Don't think she isn't thinking the same thing!)
Likewise, he won't put her on as VP. Clinton Inc could bump HIM off.
Aren't democRATs lovely people?
