“(back ten, states’s rights were assumed to be a valid political theory)”
According to the Constitution it still is.
Elitist, statist, Democrats and other liberals have been working hard to eradicate it but the individual rights of soverign states is still in the Constitution for all to read.
Jefferson, Luther Martin, et. al were right. Hamilton, Adams and the Federalists were wrong (Washington will alwyas get a pass from me.)
