It seems to me that logical thinking would imply that legislation has to be a compromise. The other alternative is one party dictatorial rule.
Newt Gingrich, recently wrote that the Republicans should not deal with the Democrats at all. He thinks they should just deal with the American people. Problem with his logic is that the American people are divided as well. There are at least as many hard core liberals as hard core conservatives.
I think most people are more in the middle with almost equal numbers of minority opinion on either the extreme right or the extreme left. That means that if government comes from either extreme right or extreme left it must become a one party dictatorship. Otherwise it does have to be somewhat of a compromise.
Compromise tends to maintain the status quo, which, I know, some folks feel is unsustainable. Folks on the left might feel it's unsustainable due to climate change, for instance. On the right, folks feel it's unsustainable due to the growing federal debt or increasing numbers of folks immigrating to USA.
Still, the status quo is what supports the lifestyles of most people. Revolutionary, or catastrophic change would be more like a dictatorship.
Incremental change and at least some spirit of compromise seems to be what works best.
