Wesley Clark is still my favorite proposed candidate. Gore has plenty going for him too, though I think like Hillary nominating him could mobilize the right a lot more and potentially cost us the election. Bayh I generally agree with, but I don't think would be a good choice. I think his somewhat ambiguous stance on Iraq would cost him a lot of moderate votes. And his DLC background would alienate our base too much. Maybe he could run in another 4 or 8 years after this whole Iraq mess is over with.
Wes Clark is a good guy but he seems to lack even the most basic political skills.
