uh...... did you hear the mealy-mouthed Mitch McConnell... the GOP is not going to do anything, they are a bunch of spaghetti-spine wimps.
If, in fact, this clause makes permanent all or part of this bill, and if, in fact, it is unconstitutional, and since it is sure to pass, the best thing the Repubs can do is let it pass quickly. Court challenges could then tie it up for years. It is inconceivable to me that the Constitution grants authority to one Congress to forever ban the next Congress from overriding ANY LAW.
