marylb:Edwards and Nunn were just announced two days ago as on the short list. All theories aside, he was in the running.
Nunn is possible because he is incredibly old, damn near a Bushiehead, and Georgia could be winnable. He's Joe Lieberman without the beanie, except socially more conservative. He'll be seen as Darth Cheney to Little Barry's George Bush.
Edwards, a politician I like and one I would have prefered to Obama as nominee, can't win his homestate and doesn't come with his own bloc. Never a serious consideration if Democrats' intent is to win the election.
Richardson or Sebelius are much stronger choices, Hispanic or Sisterhood, and Sebelius could swing Kansas and has solid Ohio roots from her dad.
