I do not mean to say that we won't have one, or that we could possibly avoid one. Where we are, a titanic struggle is all but inevitable. The sides have too much to lose. A political compromise would in principle be easy -- the Senate could advise the President whom they would find easy to confirm, and the President could nominate one of those people.
In practice it is impossible.
For the Left it is impossible because with the opportunity to create a 5-vote progressive majority bloc on the SCOTUS, the Left has in front of it the opportunity to dispose of the Constitution as an objection to their program. From now on, they would be able to simply wave away any suggestion that a policy or institution or regulation was unconstitutional because the bloc would vote to endorse it. Laws contemporary to the Constitution, which have coexisted with it for hundreds of years, will continue to be found to be unconstitutional even though neither the generation that wrote the Constitution nor any of its descendants to date have seen any conflict. It will be the end of the Constitution as a limit on government power, in other words, as long as that government power is exercised in a progressive direction.
For Republicans in Congress it is impossible because the rise of such a bloc would put an end to their major reason to exist. They would no longer be able to legislate as a party, because any legislation a Republican Congress passed would be set aside on appeal. So too Republicans in state houses, and indeed Republican governors. At a time when the Republican Party holds both houses of Congress and the vast majority of state houses and governors' mansions, this one person -- this one seat in one of three branches of government -- could effectively strip their entire power base of legitimacy. They could no longer proceed as the loyal opposition, raising procedural or legislative bars. They would be told what they could and could not do at every level of government, having their achievements thrown away and their concessions enshrined in Constitutional law.
Nothing could be clearer than that the Federal courts have become too powerful. Admittedly, this is an old argument for me. I've been arguing it probably since I've been writing here, certainly since 2006 (see "The Judiciary" here). The most important work we could do right now would be to strip the Federal courts, and the Supreme Court, of much of their authority. The Supreme Court's ability to amend the Constitution on the fly has risen at the same time that increasing diversity in the nation has made amending the Constitution legitimately, through Article V, more and more difficult to accomplish.
The Supreme Court has become much like the One Ring. Instead of trying to use that concentrated power to defend our position, we need to destroy the power lest it fall into other hands.
Win or lose this current fight over the seat on the Court, Governor Greg Abbot's suggested Constitutional amendments should become the #1 priority of the conservative movement. They are not extreme. They are not even radical. They impose only the kind of super-majority controls the Founders often invoked as guards against concentrated power.
It is in the interest of nearly every American to disperse this concentrated power, which is a threat to the peace and stability of the Republic. Unfortunately, I suspect the siren song of power -- of finally being able to force the other side to submit and obey -- will prove too strong.
The song is an illusion. No submission will be forthcoming. Beware that road that leads only to war.
