I think the NRA's brand is irredeemably damaged among gun owners under 40 or so.
Even over 40. I'm guessing my disgust with them is not typical of boomers, as I tend towards younger guy thinking on it and prefer organizations like the FPC now. Even though I'm a life member of NRA and have given them (in hindsight) way too much money over the years (but not for a long while now).
That said, even a lot of the fudd old guys have become disillusioned, and mostly due to Wayne. I've talked to a few old hunters here, a couple of them also life members, who while perhaps not done with the NRA, have been adamant about not giving them any more money for the foreseeable future.
The fact that Wayne didn't step down during the big part of the kerfuffle - when the suit scam came out - tells me all I need to know about how much he cared about the mission. Though I think my last straw with the organization was the fact that he was voted back in by the board after all that.
I don't know that the NRA will ever win me back, nor do I know if they can recover. It's not just the Wayne thing, but they have been way behind the eight ball on all kinds of stuff in recent years. They always seem to have been the last gun rights org to file a lawsuit on various recent infringements, long after the other gun rights orgs did.
