There was already a thread about this a couple weeks ago when Pelosi said the same thing.
Chet's not serious, I don't know what Pelosi is doing. Maybe she lost a bet with him or owes him a favor. She's just boosting his future political career by making his name more well known and respected.
Obama/Edwards would be really confusing and there's 100% no way that Obama could select any congressman since it would boost the "inexperience" charge that will hit harder in autumn. People won't respect a congressman with a handful of terms on the flipside of an Obama ticket.
Edwards has been a Rep. since 1991, so "a handful of terms" wouldn't stick too well.
