What Crist should do is run for a House seat against a Democrat. There are 9 other Democrats in the House from Florida that deserve a challenge. He’s got the money and he’d be able to save face. On the other hand maybe it’d be better if he just retired.
What Crist should do is go away. Besides, Governors run for the Senate or then the Presidency. The House isn't good enough for their egos level of public service.
