The nominee will be Andrew Cuomo, governor of New York. He is already positioning himself. Bank on it.
If Obama loses, whoever Bill Clinton backs will the the next candidate. The party will go crawling back to Clinton to resuscitate the party.
I wouldn’t count out Rahm Emanuel and given a choice, I believe Clinton might back RE and not Cuomo. Chicago would still be in charge, but it would be a different group of Chicago thugs.
Villagarosa will probably also be in the mix, but probably as VP material. He will probably succeed Brown as governor.
