I think there is a pretty good strategic argument to be made for conservatives voting for Huckabee, in at least a few key states.
Conservatives should vote for Huck in Florida in order to knock out Giuliani. The Rudy backers would not then default to Huck, but to somebody better.
Conservatives should vote for Huck in SC in an effort to knock out McCain.
Get the race down to Huck, Thompson, and Romney and the picture looks a lot brighter.
