Darren Samuelsohn dusts off the crystal ball and tries to figure out if the climate bill can garner 60 votes in the Senate.

Now, Crist is one of those rare environmental Republicans, and he'd be a decent bet to vote for a climate bill if he were sitting in the Senate right now. So what about his chief of staff?
