Hopefully we are all making frequent calls (and/or sending frequent emails) to our elected representatives on a variety of topics. It might be a good idea to follow up on these calls later to ask what, if any, action has been taken. Just, y’know, to prove we’re not kidding.
Consider opening a document to log your calls to your elected officials, with a different page for each rep. Show date, topic of call, to whom you spoke, with what result. If you later receive an email in reply, note the substance of the response on your log.
Armed with this documentation, you can later call back, and say, e.g., “Remember when I called you on January 6 regarding S.1629? Well, I was wondering whether you had decided to support that bill and, if not, why not?”
