The first thing NRA would need to decide is, is it going to have one "face", or several? And who is this face going to be speaking to, and what is the purpose?
Recruiting folks who already support 2A rights to join? We already know there are hordes of Threepers out there convinced that NRA is an anti-2A organization.
Changing the minds of those who think NRA members are all knuckle-dragging, sheet-wearing, militia rednecks? They call Colion Noir and Ken Blanchard Uncle Tom, so...
Convincing those who claim that they "support the 2A, but..."? that, in fact, they are only fooling themselves? I dunno. Maybe after they've been mugged...
