You've attempted to talk about states' rights, which was an utter disaster for you, and then swerved off into some other areas, which are NOT "states rights", but which you claim are, and now you're off on building contracts, still claiming that that too, is somehow a "STATES' RIGHTS" issue. LOL
Tell, me have you ever actually read the Constitution? If so, WHAT DOES THE CONSTITUTION SAY IS STATES' RIGHTS ?
Amendment X - Powers of the States and People. Ratified 12/15/1791.
The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.
