I also am sick of the notion that "moderates" elect anyone. Who is a moderate? Someone who has no convictions, or his convictions are so weak that they wave like grass in the wind. Though I disagree with nearly every aspect of liberalism, I have to respect a liberal because he does have convictions. A moderate walks outside every morning, licks his finger, sticks it in the air, and that determines his beliefs of the day.
There are few celebrities stronger in their convictions than the Nuge. I think that he went off because he was in a sense being lectured about moderation by a liberal, and he doesn't believe a word of it.
