Alaska Just Nullified Unconstitutional Gun Control Laws
The 49th state to join the Union has become the second to successfully traverse the perilous waters of nullification. In a sweeping reform, the state of Alaska has deemed that rights of the citizenry guaranteed under the state and national constitutions will no longer be ignored or side-stepped by an over-zealous federal government.
Utilizing the Tenth Amendment — which protects the rights of states to do whatever the federal government can’t do — Alaska has completely cut funding to a number of unconstitutional and illegal federal programs, including programs that violate the Second Amendment. This means enforcing those laws in Alaska is now essentially impossible.
