Forgot to ask...who is this "we" that you talk about? What gun-rights organization do you work for? Are you a politician making laws?
I know this is very frustrating to those in Blue states but think about the sea-change nationalily that has been achieved. We have some form of carry in 49 of 50 states after 15 years of hard work and improvements every year in a number of states.
Are we going to give up our successful state by state advancement to let the Feds put their nose under the tent flap and start working its way inside? Are we going to give up the barracade that presents itself to the leftist grabbers by not having to fight this away state by state with more conservative state legislators and, instead, leave the avenue open to killing our rights on the national level bit by bit as they have done with EPA and all the other Fed programs.
No, I feel for you but, IMHO, the best way is at the state level and not to open this pandora’s box of Federal control of this issue.
