Sometimes I think Glenn Beck is saying the crazy things he does just to get attention from liberals for being so crazy. It's the Ann Coulter model of right-wing punditry: the more outrageous the better for your ratings.
But Beck isn't as smart as Coulter. He's also more of a Bircherite populist, and he's convinced himself that the more mawkish the better he'll appeal to that sensibility. Unfortunately for Beck, he is also handicapped by not having a very firm grip on reality in the first place (not that this ever stopped other right-wing millionaire pundits). It shows up in his great fondness for right-wing populist conspiracy theories.
