I disagree with the Kaine hate, assuming they don't miscast him. He's not as super flashy as Warren or Booker would have been, but he's pretty well respected and regarded, and has pretty broad political experience, working his way up from local Richmond politics to Governor and Senator. I've said before that if he ran for President, he would have been my pick -- his views are close politically to Obama/Clinton wing of the party (which is where I am), without the baggage of Clinton. I think turning him into an "attack dog" would be a mistake though (as that is not his personality).
