Paul Schlicta, in American Thinker:
Obama’s Achilles’ heel may be his apparent lack of humor. He manages to affect an occasional sally at wit but he has no lightness, no human saving sense of his own absurdity. He takes himself very seriously and insists that you do the same. In short he is a perfect Victorian: a prim, humorless self-important prig.
And like all prigs, he has set himself up for all the satire and mockery that ordinary mortals will throw his way.
