For that reason, if I were a Rudy Giuliani man on Saturday, I would cast a tactical vote for Thompson, thus giving the former New York mayor a clear shot at Florida without a clear front-runner to overcome. I might even do the same if I were a Romney man seeing a Thompson surge in the state, figuring that one more loss by a suddenly shaky McCain or Huckabee in a state in which each was supposed to be strong might knock at least one of them out of the race and out of Romney’s hair. Tactically, it also makes sense for any mainstream conservative to want to give a boost to the most consistent conservative in the race, just to send a message to those who say the old Reagan coalition no longer has relevance. A win for Thompson on Saturday would tell the world that consistency across the full gamut of conservative issues still carries weight at the ballot box.
