Dr. Robert A. Thompson, President, North Dakota Medical Association
wrote a great letter that is published in The Dickenson Press. Note how it is localized and relevant to the newspaper's readers.
This can now be reproduced and sent to elected officials and others. No doubt most of them will get it from their clipping service and by sending it in from multiple sources you reinforce the message. Politicians pay careful attention to what their voters pay attention to. While letters to the editor are not read as much as the sports pages, the people who read them are opinion leaders.
This is a time-tested, effective, cheap and easy technique to influence elected officials.
