After reviewing the 2007 Senate vote ratings at the nonpartisan National Journal, I'm starting to make sense of Joe Biden as Obama's VP pick. The Obamessiah has promised to unite the country, despite being the most extreme leftist in the entire Senate. That's where Biden comes in:

Obama could have gone with the second most extreme leftist, Sheldon Whitehouse. But in the spirit of bipartisan cooperation, he went for the third most extreme leftist.

If he really wanted to build bridges, he could have picked Socialist Bernie Sanders at #4. But no doubt Obama was advised not to go overboard and risk alienating his base.
