It would be helpful for the Congress to impeach several of these judges for being partisan and exceeding their authority thus violating the Good Behavior condition of their service in the judiciary. The Democrats in the Senate will never go for it but just being impeached will shock and frighten the entire federal judiciary AND will make squishes on the SCOTUS like Robert realize he’d better step in and put a stop to this because this is really harming the legitimacy of the judicial branch.
Congress could and should also clip their wins by doing things like removing funding for any clerks for these judges, removing federal marshals from the courthouses (the judicial branch shouldn’t have enforcement power anyway), disallowing their expense claims, etc. The Congress could and should also expressly limit the power of federal judges to issue nationwide injunctions and TROs. They should be limited to the specific parties involved in the suit at hand. The congress can do this because all federal courts are courts of limited subject matter jurisdiction.....and yes over 30 years later I can still hear my 1L con law prof repeating that over and over....
