Ed Brayton has an interesting post examining whether Ron Paul is a Dominionist. The best he can come with is maybe yes, maybe no. Among other things, apparently Rep. Paul has close ties to someone named Gary North who was on his staff for a period of time. North is a wingnut who declared:
So let us be blunt about it: we must use the doctrine of religious liberty to gain independence for Christian schools until we train up a generation of people who know that there is no religious neutrality, no neutral law, no neutral education, and no neutral civil government. Then they will get busy in constructing a Bible-based social, political and religious order which finally denies the religious liberty of the enemies of God.
Brayton acknowledges that guilt by association is not compelling evidence. It raises red flags, but nothing more. At worst, so far, Rep. Paul says things that can be read as Dominionist code for less palatable opinions or as a more moderate point of view that recognizes that the government must accommodate non-Christian thought.
The intersection between “dominionists” and libertarians is strong with respect to free market economics. They reach the opposite conclusions with respect to most social policies.
