John McCain is simply a man of considerable character, poor guy. He is utterly bereft of cultural cachet. Against an animating message of cultural “change,” he is retrogression itself. Worse, Mr. Obama’s trick is to take politics off the table by moving so politically close to his opponent that only culture is left to separate them. And, unencumbered as he is by deep attachment to principle, he can be both far-left and center-right. He can steal much of Mr. McCain’s territory.
