Novak reports that Obama and Edwards might be laying out a deal wherein if Obama wins the Presidency Edwards would become the attorney general. This falls into line with my assumption that Edwards is trying to help Obama out. This could be just a rumor, but seeing how Novak has a history of snitching, it might be true, and if that's the case then this race just got a bit tighter.
By the way, Edwards as AG doesn't sound too bad. It would give him all the time in the world to tackle corporate malfeasance.
