My dad says Biden.
I am going with Jack Reed. Catholic, middle-class background (translation- does not have 7 houses) military, good committee assignments, not much negative out there, is pretty low-key but seems to be the quiet dependable type who is not gaffe-prone, but is patient and will lay out a methodical argument when he is on the Sunday news shows. Just seems like the plodding and deliberate kind of guy who fits in with the way the Obama folks operate (NO DRAMA, then counterpunch quick and hard), and he will not overshadow Obama. Additionally, since the GOP has been hammering Obama on the celebrity nonsense, a stable, serious guy like Reed would balance the ticket (Biden and Clinton would add a lot of volatility). Plus, the Obama campaign has gamed this pretty well, and Reed would be a real surprise.
If I had to go with a wild card with one dollar and long odds- Wes Clark.
*** Update ***
Was watching Larry King Live, and if Lars Larson is not the biggest douchebag I have seen on tv in a while, I do not know who is.
And Tanya Acker is just smoking hot. Period. She could be in movies.
*** Update #2 ***
From the news coverage, it sure seems like the media are convinced it is Biden.
