Jim Geraghty apparently thinks so, based on that Q-poll that currently has him barely winning a three-way race and the news that former Senator Connie Mack has quit the Crist campaign after the governor vetoed the education reform bill. And I will admit that yes, Governor Crist could run as an independent. Governor Crist could also repeatedly slam a silverware drawer on his hand until he passes out from the pain; which would be the rough equivalent in terms of results. I’m sure that people are telling him about Lieberman and Specter; but Lieberman didn’t preemptively reject his party prior to the primary (or at all, really), and the real race in PA is over which party gets to make sure that Arlen Specter returns to private life.
Granted, Crist could still do it. Hope springs eternal, right?
PS: Rubio for Senate.
