I don't know if I'm going to "unregister", but everytime I get a letter from the GOP asking for money, I think I will send it back unopened. That way not only will they get nothing from me, but they will have to pay the postage for their mail.
If enough people did it, they would get the message quick. No more money from me!!!
Don't send the request back unopened - include a note as to why you aren't supporting them anymore. I've been doing this ever since GW called the Minutement "vigilantes". At least they have to pay the return postage and I get a teeny bit of satisfaction. Not that it has helped anything...
Do what I just started doing - Mail back a peso!
