Yes, thank you, I learned the Preamble from Schoolhouse Rock; but I still believe that the United States is a union of 50 free and independent states. The Tennessee Constitution uses those exact words: "free and independent state." To me that means that the citizens of Tennessee can govern the state of Tennessee in any way they see fit.

I think in the last few years, the Colorado anti-gay legislation, the California legal pot legislation, and the arguments against the Brady Bill have ALL been about state sovereignty. So maybe it's dead in practice, only because the Fed has killed it, but it lives on in the hearts of individual citizens. :)
