What about Gen. Wesley Clark (USAF, Ret.)? Of course, I’d prefer to see him as president rather than vice-president, but being originally from the Clinton camp, he might not get enough support for it. As far as Hillary is concerned, this might be the best choice she can make, to get more centrists and disillusioned republicans over to her side. What a great strategy! Like adding chocolate sauce to a raw herring to make it more palatable! I guess it all depends on how much you like chocolate sauce.
What about Gore? Just kidding!
What about Kucinich? No, seriously…
