If you don't run, VOTE. (Vote if you do run, for that matter.) There is a lot at stake locally and in your state, and the ability for one person to make a difference in these elections is very high.
I know it feels like we just did this, but voting is like doing the dishes or laundry -- you have to keep at it. Unlike housework, you don't want to designate one person in your community to handle the chore for everyone else. (Let's be honest, they would probably fold your shirts wrong, too.)
