A rare insight:

“Substance,” here, is beside the point, and this enrages a certain spectrum of the intelligentsia. As for Barbara Bush, her husband had not one iota of star power; her son had a little, but his qualities—non-eloquence, an Everyman outlook, a red-state appeal—are Sarah Palin’s, too… a closeness that may embarrass Barbara Bush more than a little, and really sting.
