"Meeting with a Member of Congress or staff
Meeting with a Member of Congress is the most powerful way you can communicate with them. It shows that you are committed and together enough to organize the meeting, and in-person communication is more powerful than mail/fax/email.
The most important thing to remember is to be respectful but not star struck. These people work for you. You are important to them, because you are a voter, and/or because you have the capacity to influence other voters. They are responsible for hearing you out."
