Well, even if they're not insolvent, it's not good optics, especially with the NY and other AGs saying they're going to put the NRA out of business. Also I guarantee 46/Harris will use this as a "we're winning". it might even give them a positive perception for new gun laws.
I don't know what they were ever doing in NY in the first place. Also, I do question their finances, because it seems to me that a lot of people have been like me, and holding off donations because of stupid Wayne.
