With simple majorities you could, as I’ve previously suggested, bring back the requirement for three-judge district courts when the legality of federal statutes is challenged, and expand that requirement to include challenges to executive orders.

Another thing you could do with simple majorities ... is to strip federal courts of jurisdiction to issue Temporary Restraining Orders and Preliminary Injunctions in the class of cases that we’ve been seeing. Or, indeed, to strip them of jurisdiction to hear any complaints regarding the internal administration of the Executive. Or stripping courts of jurisdiction to issue any order in such cases until an appeals bond has actually been posted by the moving party.

These are all things that could be done with the existing legislative majorities, and that would do more to address existing problems than impeachments, with less of a downside.
