I absolutely agree. Our massive email/fax/letter/honking campaigns have resulted in absolutely nothing. We made our voices heard, and they just don't care.
Keep writing regardless; when they ask indignantly, "Why am I being recalled?" or "Why am I being removed from office under charges of Treason and/or violation of my Oath of Office?" we can start by saying, "Because we spoke up and gave you a chance to represent us, and you ignored us."
