Look at the US house of representatives- (That's Congress, rather than the Senate, for anybody who's not a West Wing addict, etc)
Elections every two years, and so it's an almost permenant campaign.

The Senate, with six year terms spends more time governing, and less trying to get re-elected.

Does this make Congress any better behaved, efficient, representative or cheaper the the Senate? I would say the opposite.

The UK. The Commons Vs the Lords. I know which I think is better behaved, efficient and representative. And it's not the on I voted for.

Of course, when all the decisions are really made by an old man who lives in a hut, and talks to his cat alot, then we'll be fine, Unless one of the seven people who know where he is is a lawyer.....
