Construct your dream ticket, taking into account all factors -- issues, electability, geography, looks, age, names, race/ethnicity, reputation, and everything else you can think of. Of course, I'm thinking real live people, so, unfortunately, Wellstone is out.
Mine would be Harkin/Richardson, I suppose. Maybe Harkin/Edwards. Maybe Feingold/Richardson? Maybe I can get former OR Gov. John Kitzhaber, M.D. in there somewhere too. Good populist, progressive background, impeccable DC and foreign policy experience while still not considered major insiders -- those are my criteria.
