Rule #3: “Remember Who Elected You.” On many of the big issues, there are at least two responsible and reasonable positions if not an even greater number. Presumably, if you're an elected official, you were elected because of the positions you took. If you were elected as an environmentalist, be an environmentalist. Do what you said you would do. After all, you got the majority vote. That's why you were elected.
Rule #4: “Go Where You're Invited.” In other words, never be afraid to open up a dialogue and discussion with the people who didn't elect you. You might learn something. This is an antidote to Rule #3.
