SCOTUS has said, loudly and clearly, that state courts can rewrite laws and usurp Constitutional authorities on a whim.
How is that a loss? At this point in time, I believe most states have Republican governments.
I'm no more in favor of Republicans modifying the law on a whim than I am for Democrats doing it.
Actually, at least in terms of the law, SCOTUS has done no such thing. It says repeatedly that its refusal to grant cert has nothing to do with the merits of a case.
In this case, SCOTUS, in Bush v. Gore, laid down the law, and a lower federal court is perfectly capable of enforcing it. Let us see what happens to the absentee voters' suit in federal district court in Trenton.
