A lot of things going on in New York State. First, you have a very angry, and power-hungry Governor. There is no doubt that she has ambitions beyond being Governor of NY. The new firearms law actually got rolling after the mass murder in the Buffalo supermarket. Once the SCOTUS tossed out their handgun law, it pushed her over the deep end, and she acted out of emotion (anger) rather than reason. And because she has a democrat-controlled State legislature it was easy to ram-rod the law through.
It was the same with Roe v Wade. As soon as SCOTUS over-turned it, she again acted with emotion (anger) and signed laws protecting abortion in NYS. Fine. The SCOTUS simply overturned a bad decision and put it back on the States to decide.
SCOTUS is not real popular with democrats right now, even though they loved them when they upheld Obamacare, and made gay marriage lawful throughout the land. But now because they hate Trump, they hate the SCOTUS because he was able to place three justices on it. The anger also stems from McConnell effectively blocking Merritt Garland, which was a wise move since Garland proves every day why he was unfit for the SCOTUS.
Now like little children they act up, create accusations against nominees, make a scene, and cry that the court is illegitimate, illegal, radicalized, rogue, outdated, and we need to pack it to have "equity." Never mind that Schumer would have done exactly the same if he had the chance. And make no mistake, the attacks on Clarence Thomas are only beginning. His ouster is next or at least planned with their next agenda.
So, you are seeing not just the Governor of New York but democrat Governors of other States acting out because they are upset that a decision did not go their way. The political divide has also spread to judges at various levels, many of whom on either side now make rulings or block things based on their political view rather than how the law is written. Yeah, I know what the law says, but I think it should say this. Or an outside lobby works to find the right sympathetic judge to block or stop something. That is where we are today.
The political ideology, anger and divide runs deep. It is affecting everything, not just firearms laws.
The best and most patriotic thing you can do this November is vote against every single democrat on your ballot, right down to school board members. And do that in-person on Election Day. Avoid early and absentee voting. JMHO.
