Speaking of gun control -- Wyoming state legislators are experimenting with nullification.
In a bill sponsored by eight representatives and two state senators, the lawmakers stipulate that “any federal law which attempts to ban a semi-automatic firearm or to limit the size of a magazine of a firearm or other limitation on firearms in this state shall be unenforceable in Wyoming.” These two measures have been among Biden’s proposals. The Wyoming bill also makes it a felony to enforce federal gun laws.
I'm old enough to remember when conservative states threatened to nullify Obamacare, but they never followed through. Probably because doing so would be blatantly unconstitutional.
