"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."
The Tenth Amendment is very clear. The federal government has been running roughshod over it for quite a few years now. Simply put (if I can say it any more clearly than as written, which I doubt), the federal government cannot take powers away from any state unless that state yields those powers to the federal government voluntarily. The only exceptions are in the Constitution, nowhere else--not in Congress, and not in the White House. They cannot be legislated away or executive-ordered away.
This fight has been going on for a while. It seems to be yet another salvo.
