1) The No One Is Above the Law Constitutional amendment
2) Term limits for Supreme Court justices
3) A binding code of ethics for the Supreme Court
Now, there will be MUCH MAGA whining about this, and I fully expect Millerscum, stupid Tom, Boilerboob, and Angry Jerry to tell us why these are bad ideas, using their usual ineffable logic. But they can relax. None of these reforms will become law--the Republipigs have too much power to let them pass, and will retain enough to block them even if they get their clocks cleaned in November.
Biden knows this. So, what's the point? The actual object is to put it to the MAGAs. You object to/vote against the amendment? Why? Are you still harboring fantasies of serving in the royal court of Emperor Trump? No code of ethics for SCOTUS? Why not? You want plenty of clearance for Clarence?
Ask your MAGA friends/acquaintances/enemies about this. It'll be loads of jolly fun to see them twist themselves into pretzels to explain why these are bad ideas.
