...Electric Term Limits
Would term limits on Congressional positions help or hinder the democratic process? If you were limited to a single six year term as senator and perhaps two or three terms as a House representative, would it free people up to vote in their legitimate best interest for the nation rather than concern with how it would affect their polling? This is the same reason why we appoint Supreme Court Justices for life but obviously we're not looking to elect Congressional representatives for life terms.
I've heard people on both sides of the partisan aisle before bemoan the fact that we have "career politicians", especially in Congress who's primary motivation (for purposes of the argument, I don't know if I fully believe it) is to get re-elected and keep their job. The purpose of the short House representative term was to promote a continual churning of new people in that chamber. Instead, out of 436 seats, we see perhaps 50-60 of them honestly contested each election cycle.
Obvious downsides would be that you'd lose policy experience in Congress, each member would be spending the first part of their term on a learning curve and sometimes the guy who is in there is legitimately the best guy running for the job.
I know that this won't ever happen. Hell, it seems that half the time when someone running "term limits" himself in his campaign pledges, he breaks it anyway. And the people who'd need to enact the changes are the same people who are the so-called career politicians. But what the hell; let's discuss it.
