As Larry Sabato points out in the Tweet Tracker, Crist is going to have to go hard negative against Rubio now. So we’re basically going to watch a politician without a core (witness the brazen flip-flop on stimulus and the appointment of a placeholder friend to the Senate seat) trash a politician who has the qualities to become a national star (young, dynamic, Latino, and conservative). Crist will have to stand in the way of the GOP future, yelling “Stop”!
