(at least for Obama....if he gets that far)
In no particular order
*Tom Vilsack (Unfortunately a Clinton supporter at the moment)
*Gen. John Batiste
*Rep. Mike Thompson
*Russell "Russ" Feingold
*Gen. Anthony Zinni
*Rep. Jim Marshall (Jim Marshall would be a nightmare for Republicans).
*Wesley Clark (Clinton supporter unfortunately....perhaps he'll come to his senses)
*Tom Daschle (barely a good choice... may be seen as too weak or divisive. He also lost his Senate seat & leadership position in 04. But because of his support for Obama, he is someone that Obama may be considering. Very experienced political leader).
This is not a full list... but this would be a good start. Half of those listed are Vets.... the kind of VP candidate that Obama may want to have on his ticket in a General Election matchup with McCain. However, the non-vets are also good choices. He probably couldn't go wrong with any of the above. Although some are supporting Clinton at the present time.
Who do you think Obama will choose as his VP running mate?
