This, in a nutshell, is Mitt Romney's biggest problem. A late immigrant to conservatism, Mr. Romney doesn't speak the language naturally. He shares traits with both Al Gore, whose stiffness bordered on the animatronic, and George H.W. Bush, whose contempt for the song-and-dance of elections was transparent. Mr. Gore tried to compensate for his inadequacies by shouting, like an ugly American who thinks a foreigner will understand him if he only talks louder. Mr. Bush fell back on recitations of patriotic slogans and the generosity of providence that delivered Michael Dukakis as an opponent.
