I too am old enough to remember Bush, and honestly... I think this person is seriously underestimating how much more dangerous the Republicans have gotten in the intervening time.
Bush had nothing remotely close to the project 2025 agenda, and Bush didn't have a supreme court willing to tell him that he was literally above the law.
Bush was terrible, no doubt about it, and the people who've been trying to rehabilitate him can fuck off forever. But Trump, and the version of the Republican party behind him, are so much worse.
