These Never Trumpers and people like Nicolle Wallace and Cupp really believe that if Trump loses, they're going to once again be held as credible conservative voices, demanding that conservatives hold their noses for RINOs. It just ain't going to happen, ever again.
If Biden wins, the Left will be out for blood. The very first people who are going to be cut loose are the Never Trumpers in the GOP establishment. They will not get invites to the fancy cocktail parties, because the Left is going purge the Hell out of everyone who opposes them. Guys like Romney and Kasich are just going to be ignored.
Cupp is just a total idiot and a sell-out who sold out for the D.C. limelight.
They believe that they will control the Republican Party again, and that the America First conservatives they betrayed will stand shoulder to shoulder with them, and obediently vote for the next Bush / McCain / Romney.
