Primarying these gutless wonders of the GOPukes is so very crucial.
Stop it. Replacing one despised Republican with another RINO-in-waiting is pointless.
Burn it down. Fresh start.
The people want two things the GOP is never, ever going to give them - social conservatism enforced by state power, and interventionist economics to protect the common people from finance capitalism.
A weak liberal democracy with libertarian leanings never has, and never will, defeat a bolshevik insurgency of the sort that is sweeping to victory all over the country.
Form a party to give people something they want - which does not include tax cuts and foreign wars on behalf of alien peoples - and you will take power.
Fail to do that, and you will have racial socialism, secret police, and communist economics.
Your call - but until the GOP is burned to the groound, the communists will just keep winning.
