Eh, I don't particularly like the pick.

He serves as the chair on the subcommitee of crimes and drugs. That makes medical marijuana a zero possibility for another 4 years.

It's a safe pick. I would've voted for Obama if he picked Mark Warner, who proved he turned a deficit into a surplus and brought a lot of money and jobs to Virginia thanks to his business acumen. Biden is another experienced beltway insider, which I suppose is why Obama picked him.
