I hate term limits. They are un-American. If the voters want to elect someone twenty times, that is their perogative as voters, and we shouldn't tell them who to vote for.
The Articles of Confederation had term limits. Term limits were considered as part of the Bill of Rights. The Founding Fathers never conceived that a political class would develop that considered their occupation to be Representative or Senator. It is un-American in a Republic to have single individuals serving for long periods of time.
