My vote for VP goes to the sneaker Gov Ray Mabus. While he might not help deliver VA like Kaine, he couldn't be better fit for Obama's needs:

Highlights:
-Served in the Navy
-Ambassador to Saudi Arabia
-Executive Experience as Governor of Mississippi
-Also has law degree from Harvard
-Social Responsibility Award from the King Center in Atlanta
-National Wildlife Federation Conservation Achievement Award

And he's a great surrogate already:
