I understand that’s clearly the intent, but if Biden (say) arrests the entire SCOTUS, or cancels the election, or declares Trump a seditious traitor & slaps him in jail, who’s going to stop him? It would be “an official act”, & he can just ignore the yowling from the MAGAs.
And he wouldn’t need to wait for a court to recognize the legality or constitutionality of his actions; he can just point to Trump v. U.S. and say he’s doing it “for the good of the country.”
I’m using extreme examples I don’t think Biden would ever employ, but what lesser thing might he do?
