The 2012 nominee will be a Governor or ex Governor. Republicans cannot afford to run anyone legislative after bashing all of them so hard for the last few years. It won't be Romney or Huckybuck, who are seen as has been also rans. Jindal's too ethnic. Pawlenty is too Right Wing whacko. Halley Barbour would be a great choice but he's too blatantly deep South.
My guess, Mitch Daniels of Indiana. Bland. Successful Governor. Not a sex fiend as far as anyone knows. Not much of a paper trail.
What do I know? They'll probably go with the Salmon Slut.
