I called the NRA ILA yesterday (Friday, 7/2/2010) at 1-800-392-8683 and punched option 4 so I could speak to a person.
I told them that if they endorsed Harry Reid, I would cancel my membership, ask for a refund, and promote joining alternative organizations at my gun club (since membership in the NRA is one of the few requirements for joining.)
They didn’t say a whole lot. Pretty much, they said, “OK”. It was just some low level minion anyway, but I’d rather talk to a person and get some minimal feedback than just leave a message on their “hotline” or whatever it is they call it (Option 3). I know for sure I’m wasting my time doing that. I also filled out a comment form on their ILA web page, so they also have a written record of my comment.
The NRA won’t give you a refund.
