OK, what do we need?
1. Someone to the right of Kerry
2. Someone from one of four regions: Rustbelt, Southwest, Iner Midwest and Missouri, or Florida.
3. Someone who will definently carry their home states, and is from a swing state.
Tom Vilsack, Governor of Iowa. Mid-left, very very popular here, and with workers. Would keep Iowa, help lock in Wisconsin, Pennsylvania and Michigan, wouldn't hurt in MN, might help in MO, and would probably halep in Ohio as well. He would be a good choice to stop any slide.
To have someone to gain states is harder. This is where Edwards would come in if he was from a state like Ohio. Do we have any charismatic Midwesterners, who would win their state and help in their region, is to the right of Kerry, and is from a swing state?
Any bets it will be no-one mentioned in this thread, although I have no idea who it will be. I would like to have an Iowan VP for sure though
