I agree with you as can see from my posts on this thread. As a group we are definitely in a Foot Shooting Mood.
How else is it that a RINO will become an "unelectable candidate"? We've done the "support the nominee" routine for sixty years. The RINOs have not changed. They still actively screw conservative nominees regularly. Incrementalism is nice pleasant strategy. The problem with it is that once in the majority the RINO/Crat party forces "moderate progressive" policies that produce a declining culture that results in a ruined economy... with "Republicans" taking the blame. Look at what was done to California. That strategy produces Democrats. That is the future of your strategy.
