i'm not going to address the predictably silly aspects of this article, at the national review. conservatives are very silly people.
but, it is not hard to predict what would happen should this take off - whenever a new president takes over, they'd rotate the judges in that they like, and rotate the judges out that they don't. so, what was intended to be a check on power would become a rubber stamp.
i understand that the american left is very apprehensive about the court skewing to the right, but it has to look at this in the longer arc of history and just fucking deal with it until it can regain control using more appropriate measures. i may support shrinking the size of the court somewhat, but my official position is actually to suck it up and wait it out.
that said, there are ways to lure a judge off the bench. maybe one of the conservative judges might like a nice, cushy job as an ambassador to the virgin islands, for example.
