One can only hope McCain fails to get the minimum candidates and the Republicans actually have to find a candidate at the convention....I would say Newt is working in the wings to this end positioning someone to sweep up the pieces.
And....all the delegates do not have to vote as elected...many can pull the plug with a good enough reason. Lots of time left. Romney got high votes on Tuesday in part because people like a "winner" between he and Huck.
