1. Do write / call them. They don't know what you don't say. The cardinal rule in politics is that people only contact politicians when they are opposed. Be sure and let your Senator know when you support them. If you are going to write or call them - learn the how the mail works, and how to leave a message (include name, address and phone number). Don't send in a form letter!
Please note that each Senate office will handle mail slightly different, however this post is general enough that it should apply most everywhere.
I will only be talking about mail from constituents, meaning people who are writing their duly elected representatives, and not someone else's. (See journal post of do's and don't of contacting your senator.)
Also please know that there is a delay in your mail reaching your Senator (it's about 3 days right now).
