Why have Obama's approval ratings dropped so much recently? Are people too stupid to see his greatness?

RealClearPolitics averages several polls and has him at 57.8%. That's his lowest approval rating yet and it would be even lower except that they still have a poll from ABC that's 3 weeks old and has him at 65% mixed in with the latest ones that are far lower. What has happened in the last month to make his numbers take such a dive? Do Americans not see the miracles that the stimulus has produced? Are they too crazy to see the benefits from Cap and Trade or the Universal Health Care bill? Bah! Shoot them all I say! The Glorious Revolution must continue at all cost!
