It will be Edwards.
It might be Edwards, but choosing any RAT Senator -- current or former -- is a huge political risk for Kerry. We can run ads that contrast Kerry's extreme liberalism vs. his own running mate on issue after issue, particularly taxes and defense.
My money is still on Gephardt. He is popular with all factions of the party, is experienced on a national scale, puts Missouri and other midwestern states in play. Labor loves him. And he is no threat to PIAPS in 2008, which eliminates Edwards.
