We talk about "Fredocon" conservatives. Fredo, in The Godfather, was the weak son of Don Corleone, who betrayed the Family to their enemies, in exchange for a promise of being put in charge after the Don, Sonny, and Michael were dead.
We have real Fredo-types, the people who only care about keeping donor cash flowing, and will compromise everything for that. The Boy Scouts were destroyed as a conservative institution because the board cared more about corporate sponsors who wanted the Scouts to stop excluding gays, than about the boys they were supposed to care about. The RNC cares more about corporate donors who want free immigration than about American citizens.
That's why I voted Trump. I figured he was rich enough to not be as interested in getting paid off.
Traitors is the proper term.
