Some interesting steps being taken by a number of states lately:
State Sovereignty for New Hampshire
Missouri claiming sovereignty under 10th amendment – HR 212
Arizona Warns Feds To Not Tread On 10th Amendment
Maybe Oklahoma started a domino effect with its legislation?
Here Missouri’s house bill #212 is qoted, which is in reference to abortion, which is an important issue, but I think HCR13 is a more general bill which needs to be supported 1st, then we can duke out the abortion issue amonst ourselves.
