I could care less what you and Sherwood Boehlert think. We have an irresponsible, out of control, black robed punk in Florida who wants to kill off Terri. In such a situation it's great that Congress is going to try to nullify his rulings.
But remember. All Congress has done is throw this case into Federal court. No one knows what this Clinton appointed judge will do.
(Denny Crane: "Sometimes you can only look for answers from God and failing that... and Fox News".)
While I do not support Congress's action in this matter it is completely within its prerogatives to increase federal court jurisdiction. The USSC refused to hear the initial appeals because it had no jurisdiction under federal law.
Hence, Congress, AS IT IS EMPOWERED by the Constitution to do expanded that jurisdiction to allow the case entry into the federal judiciary.
BUT, and it is a big one, the Judge will review the findings under FLORIDA law not federal. Since the finding is more than likely to be that the courts have followed Florida law the tube will remain pulled. Thus, nothing will change except the GOP can claim it tried to do something.
