If national action were our only option, I'd be inclined to agree with you. But states still make most of the laws and state judges still decide most legal disputes. Furthermore, judges in some states are elected, not appointed. And some of those states permit campaign contributions from out of state.
So find a state more conservative than the national average and possessing all of the above positive characteristics and concentrate your efforts there. Perhaps the best prospect for such effort is Alabama.
I think we're fine here in most of Tennessee.
I don't see state judges with the death ethic of Greer.
