About 30 years ago liberalism and conservatism could probably be defined by the positions of Hubert Humphrey and Barry Goldwater. Moderatism would be when they compromised their respective positions to "meet somewhere in the middle".
I'm inclined to think that a broad spectrum of views in the Congress is a good thing, as it will hopefully boil down to a moderate result. I also think that the President should be a moderate.
I think it can't be a good thing for the Presidential leadership to be swinging between extremes from election to election.
