Obama veepstakes predictions?

Five Thirty Eight analyzes the betting markets for Obama's vice-presidential pick, which will almost certainly be announced sometime this week.

As I've said before, I think Biden would be a great pick -- granted, he's flawed in several ways, but so are all the available options; there is no perfect choice -- but I somehow just don't think Obama will go that route. That said, I honestly don't know what he'll do. In his heart, I bet he wants to pick Kaine or Sebelius, but there are major problems with either option. Reed?

What are your predictions?
