Actually, the poster above who referred to Congress is probably more near the solution. The Supreme Court is usually the "caboose" of the three cars of government. The President and Congress are more suited for leading sentiment/policy while the Supremes usually follow public sentiment/policy. (I am not saying that the Supremes never lead--abortion and homo rights being examples--only that they usually follow).
Yes, maybe but it seems Thomas's opinion was so clearly following the Constitution that the dissenting decision by the court was in fact justified on Constitutional grounds without having to go to congress. Yes they are the 3rd wheel and rightfully so but isn't that their purpose if an issue comes before them to make sure it follows the Law of the Land. And this clearly was not interstate commerce... IMHO
