Sure but that’s not countervailing laws.If a state law says all citizens will a right buy, possess or carry a class of gun a locality cannot oppose that positive law. Now if Colorado say tailored their law to say handguns then under the right state constitutional circumstances a locality could theoretically restrict other classes of guns.
In New York the state has laws allowing the purchase of guns.... New York City has many additional restrictions on top of state law.
Twitter is nuts. Hopefully Trump can come up with something better. Or at least someone, even it isn't Trump.
So? Remember the constitution guarantees for states to have a Republican form of government. That’s it. It has no protections or positive rights for localities. How the individual states organize themselves and their localities is up to the states. The point is each state is organized differently. The constitutions of New York and Colorado are going to be very different. How the counties and localities can govern themselves is up to the states. I really would suggest you start looking at that and “positive laws” and “negative laws”.
