Pros: Because he's been out of DC for 4 years now (and was only there for 6), JRE does reinforce Barack's change banner, despite the fact that he was the Veep nominee in 2004. With his southern background and twang, the hope is that he would help win the white swing voters that they pundits have deemed crucial. He seems to have a good working chemistry with Barack and selecting Edwards, and putting Elizabeth Edwards back into focus, could give the Edwards one final turn in the spotlight together.
Cons: His poverty work does not play well in the general election, which seems to be directed more and more at answering the puzzle of "whose domestic policy is better for the middle class?" So while Edwards' "Two-America" message gains traction in the primary, it's the America in between that the general election is more concerned with. JRE also lacks the foreign policy experience that is so needed on the ticket.
