That's not a given. I hope it does get overruled by the courts. If the courts uphold it that sets a very dangerous precedent that Democrats are dying to use.I didn't vote for McCain for President, because of his historical support for universal background checks. I didn't vote for Romney for President, because he signed an assault weapons ban in Massachusetts. I will not knowingly vote for a proponent of gun control.
Trump presents a problem in this respect. He vowed to support the 2nd, so he got my first vote. Then he f'd us with bumpstocks and his open support for red flag laws (which I don't support, and which we've had here long before he came along, I think).
Well, I figure he's going to be overruled by the courts on the bumpstock deal, and his rhetoric about the red flag laws, while offensive, did not dissuade me from voting (grudgingly) for him a second time, because his illogical opinion is not law, even though it may have encouraged others to make law.
Biden is a known advocate for disarming the citizenry, contrary to the basic protections enshrined in the Bill of Rights. There is absolutely no way I could vote for him. Every one of his positions harms the Republic, in deep and meaninful ways. It's frustrating to see people place their emotional beliefs above their constitutional protections, and to see they will not accept reason over emotion.
