A Crist Republican is somebody who believes in getting elected...and little else.
That is an excellent way of putting it. A moniker widely applicable, "Crist Republican".
Tragically it describes too many Republicans, and why I advocate a conservative third party. I have a common sense conservative friend who has said for a long time, "at least I know what the Democrats stand for."
I believe it is easier to steer the GOP towards conservatism than start a whole new party. Look at the Fla. primary, a conservative vs a political "null set" like Crist.
