Direct election of Supreme Court judges. The judiciary is inherently partisan and pretending otherwise is denial at this point.
Because of how many partisan and/or ideologically-driven Supreme Court Justices we have had for several decades, I understand why you feel so cynical. But it is not "inherent" that the Court will always be this way in the future. The Court has not always been full of nothing but ideological hacks. Some Justices have truly been objective and were true assets to our system of government, and that includes Joseph Story, Oliver Wendell Holmes, Benjamin Cardozo, and Hugo Black. If we had a Court that was filled with people like those, we should not be holding direct elections for the Court. It is too inaccurate and too cynical to hold that we can't ever have a Court that has truly objective interpreters of law. It can happen if most Americans start insisting that is what we should have.
