You are mistaken. Your enemy is expanded government liberal-socialism, not the limited government conservatism that the Republican party needs to stand for.
Party affiliation is moot. Failure to comprehend that detail sabotages the future of the Republican party. Rejecting big-government Republicans at every turn is about the only hope we have of ensuring the GOP's future success.
I’ll worry about Republicans who have strayed too far AFTER I ensure that the Democrat is defeated.
Only when Republicans have a majority again can the party be pulled back to the right. I’m far more concerned in defeating the scumbag Al Franken and Barbara Boxer’s of the world than in engaging in self-destructive circular firing squads among my friends and allies.
