Your reference to the PAC's reminded me of the story I read today of long-time GOP donor Mike Fernandez. Apparently he left the Republican Party end 2016 due to Trump, and recently a Republican fund raiser made the mistake of asking for a contribution, at which point he replied: The cracks are starting to show.“All the Republicans who hide behind the flag and hide behind the church, they don’t have the f------ balls to do what it takes. [...] I am out of the political process. Too disgusted, too expensive, too supportive of ego maniacs whose words have the value of quicksand,” he wrote in an email to a Republican fundraiser seeking political contributions.
I sincerely hope you're right. So far they've lost George Will and Joe Scarborough and I guess Hannity isn't getting the Buckley Award because Chris Buckley said something along the lines of are you fucking kidding me my dad is spinning in his grave. But I'm not sure how much of the current posse is driven by opportunism vs. idealism. I think opportunism is heavily represented.
