Last I checked, the Bush Bots wanted the Libertarians to fight within the GOP rather than be spoilers.
I haven't considered the liberalitarians to be a branch of the GOP since 9/11. It became very clear to me, then, that the liberalitarians had more in common, on the important issues, with liberals than with conservatives. I'm tired of the GOP trying to court them. They can go as far as I'm concerned.
