A wise man once told me, "never vote for an incumbent." I am realizing the true wisdom in those words.
It's not that simple.
That's why term limits are needed.
Term limits are a terrible idea. They ensure EVERY politician has one full lame duck term where they can do whatever they want as they aren't accountable to the voter next election. And when we actually do find and elect a good representative, term limits prohibits us from keeping him in office. The framers of the Constitution considered term limits and rejected them. As do I. There are things that are broken and dishonest incumbents are too hard to dislodge. So let's fix what's broken without shooting ourselves in the foot.
