While I agree that the list should cover unsolicited messages about political campaigns, I recently received a call that influences my thinking on this. Without any prior registration, my senator robo-called me to include me on a teleconferenced town-hall. I could hang up if I wished. This was one of the most inclusionary things I think a public servant could do, and it is therefore important to me to maintain its efficacy, which means keeping its user base large. I hope to see more behaviors like this and fewer of the common prerecorded messages.
