I think that damage can be done surreptitiously and collaterally. Look at what that complete moron Marc Morial did in New Orleans. We had SHOT SHOW here in Louisiana! SHOT SHOW! And this imbecile made them leave because of his phony anti gun stance and lawsuit against the gun industry!
Other ways, tax ammo (he do love taxes!), discontinue 2nd amendment tax holiday's (which he probably will anyway because he is a tax parasite), and little gambits here and there in the name of public safety.
Didn't they almost do away with the last 2nd Amendment holiday but ended up changing their mind?
