Throw out the Jan 6th example, it's now ancient history. As a party, Republicans are, at this very instant, claiming that judges are acting illegally for... using their constitutionally mandated legal powers. Simultaneously, but separately, the party apparatus is repeating on a daily basis a new conspiracy theory that the judges they don't like are being controlled by some nefarious power.
And it's a very, very well established playbook. We have many examples of countries that dismantled their systems of transition of power and division of power starting with the courts. It's a move that could pretty much make it into a "For Dummies" book.
"The value is still there." I can't see it. But maybe I'm too focused on judging on the entire scope of action and speech, rather than a very narrow bit of speech that isn't at all reflected in actions.
