He can serve as VP and possibly be President if something were to happen to Hillary. Next down the line would be Pelosi.
In all seriousness, this isn't going to happen. Americans want "change". I thought she wouldn't pick Obama, but after seeing today's debate, it seems that it is a possibility. They would win by a landslide if it were Obama/Hillary or Hillary/Obama. Obama raised 32M in January. That's 5 times more than what McCain raised in the 4th quarter (3 months

) and McCain took matching funds.
