OK, additional thoughts on the metaphysical game of Twister Clinton's tangled himself into. (And the Democratic party, in general.)
It's my -- doubtlessly oversimplified -- reading of Aristotle that politics is the practical expression of philosophy. I.e., you have a certain view of the world, the universe, ethics, and human nature. You translate that view into a political philosophy, and from there, into a course of practical action in the political sphere. After that, you find a lot of other people who sort of agree with you and try to make it happen. Political philosophy is the operating system of democracy. Citizens debate the philosophical issues first, before anything else happens.
For whatever reason, there's not much real political debate in late 20th century America.
In mainstream politics, the 45% of Americans who believe in a relativistic morality find themselves in a twisted position indeed. The Democrat party represents their philosophical worldview. But the Democratic party can't openly state that worldview -- they have to wrap it up in politically acceptable code. The result is a constant disjunct between stated belief and real belief.
To put it plainly: We don't believe in God—or not believe in God. We don't believe in an absolute code of right or wrong, either. We can't come out and say it. But the Democrat party stands for our non-beliefs. Although, sadly, they can't actually say it either.
Obviously, I'm talking about the twisted position of mainstream liberals in mainstream American politics. None of this applies to, say Ralph Nader, Noam Chomsky, the late Bill Hicks, etc. We still have a thriving -- and totally ineffective -- hard left who say exactly what they mean and get nowhere.
