As long as the government does as much as it does, and people want govenment's "help", term limits don't help, they probably would hurt. Rookie congresspersons can't know all about the thousands of things being considered -- they don't have the experience. Since they can't learn enough, they rely on bureaucrats and other experts (lobbists).
In OOP, we talk all the time about messaging. When you vote for someone who can't win, you are messaging our civilization as to what you really want. That gives feedback to the system. (Not that I have much hope for it.)

>1. Term limits on United States Congress. We must get these lifer politicians out of office. They are responsible for the stagnation of our country. They are the ones most owned by special interests. They do not work for us.

>2. Vote by Ranking. Instead of getting to vote for one person (in most cases the least worst candidate), you rank the candidates in order of preference. This is the only way to get rid of our dismal 2-party system and bring real change via 3rd party candidates. By ranking candidates, your vote for a 3rd party candidate isn't "wasted".
