The answer is to "go John Galt" to whatever extent possible for each individual. Go on a brain strike and remove your talent and your dollars from the service (subservience, really) of others. When the RINOs no longer have the $$ backing and the electoral support needed to stay in power, they will panic as they suffer one humiliating embarrassment after another from the liberals. They will finally understand that they are doomed.
Once they've withered on the vine, the conservatives can come back and establish a viable and PRINCIPLED second party.
One more thing: train your children to be warriors. It is unfortunate that the next generation is going to have to pay the price for the errors of this one, and there will be "casualties" in one form or another. Your children are going to have to be strong to deal with what lies ahead. This is the RINO legacy.
Going John Galt can be done immediately. Plus it is cheap, stealth, legal and offers plenty of days off for fishing. It will buy time while we figure out if we promote the Constitutional Party or another conservative party. Fire the republicans.
