I would not say they were “sane” per se, it’s just that they’ve been replaced by even more overt bare-faced extremists. The Overton window on what is extremely right wing keeps getting pushed more and more to the right. A loud mouth performative asshole they believe is beyond punishment due to his “billions” has given them a permission structure to be who they always really wanted to be. These are the people that didn’t understand that Archie Bunker was supposed to be a parody, not a hero.
