10 Commandments for Politicians

From Mark McKinnon at Public Strategies Inc.:

Ten Commandments for politicians:
1. Don’t lie
2. Don’t cheat
3. Don’t have affairs with aides
4. Don’t hire relatives of aides’ with whom you are having an affair
5. Don’t claim immunity because your activity is not technically prosecutable
6. Don’t use government aircraft for dangerous liaisons
7. Don’t hike the Appalachian Trail
8. Don’t go looking for that “sparking thing”
9. Don't make foreign bed chambers a rationale for chamber of commerce trips
10. Do resign when found guilty of any of the above

Not bad. What about a second 10 commandments? Any ideas? Go for the top 20 Commandments.
