Interesting quote:

There are only two kinds of politics. They are not radical and reactionary or conservative and liberal. Or even Democratic and Republican. There are only the politics of fear and the politics of trust. One says, You are encircled by monstrous dangers. Give us power over your freedom so we may protect you. The other says: The world is a baffling and hazardous place, but it can be shaped to the will of men.

-- Edmund S. Muskie, November 2, 1970 (Senator from Maine)
