Now THAT would be something! I believe the only place in Amerika right now that could defy the U.S. Supreme Court ruling without Federal action would be Kalifornia (which is basically a third world country, anyway).
Interestingly, both Jefferson and Madison advocated just this type of state response to unconstitutional acts of the national government in their Kentucky and Virginia resolutions. TheKentucky resolution is linked below. I hope you'll read it and spread the word.
