Tenth Amendment
The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.
I would bet the good people of Arizona will make reproductive choice legal just as very Red Kansas did.
I personally hope they do. The story of the 10 year old girl in Ohio who was raped and was denied an abortion was horrible.
But just as the 10th Amendment applies to reproductive rights, it also applies to the legality of automatic/semi-automatic weapons. Nothing in the Constitution talks about automatic/semi-automatic weapons.
