It's a long shot, but of all the Dem he is the only one that has been even close to being bipartisian.
Bayh can see the writing on the wall.
He has high approval ratings so the only thing I can see is he is either throwing his hat in the ring or Bayh has been making waves and the war room has decided to go to war against him.
I’m guessing he was sick of dealing with the demands from the kook left fringe that he vote for their agenda. Can you imagine the Code Pinko types camping in your office telling you to get with the program?
I really felt that Bayh was genuinely into a spirit of bi-partisanship, as well.
Folks like Warner, Webb, Landrieu and Specter are simply looking out for the next election or a higher office.
Regardless, Bayh never actually bucked the party by voting against them and their whack policies. A true statesman would have made his vote count, when it was needed.
