“Obama’s manner in dealing with other people and acting in the world fully exemplifies the cheerful impersonal friendliness—the middle distance—that marks American sociability. (Now allow me to speak as a critic. Remember Madame de Staël’s meetings that deprive us of solitude without affording us company? Or Schopenhauer’s porcupines, who shift restlessly from getting cold at a distance to prickling one another at close quarters, until they settle into some acceptable compromise position?) The cheerful impersonal friendliness serves to mask recesses of loneliness and secretiveness in the American character, and no less with Obama than with anyone else. He is enigmatic—and seemed so as much then as now—in a characteristically American way…. Moreover, he excelled at the style of sociability that is most prized in the American professional and business class and serves as the supreme object of education in the top prep schools: how to cooperate with your peers by casting on them a spell of charismatic seduction, which you nevertheless disguise under a veneer of self-depreciation and informality. Obama did not master this style in prep school, but he became a virtuoso at it nevertheless, as the condition of preferment in American society that it is. As often happens, the outsider turned out to be better at it than the vast majority of the insiders…. Together with the meritocratic educational achievements, the mastery of the preferred social style turns Obama into what is, in a sense, the first American elite president—that is the first who talks and acts as a member of the American elite—since John Kennedy …. Obama's mixed race, his apparent and assumed blackness, his non-elite class origins and lack of inherited money, his Third-World childhood experiences—all this creates the distance of the outsider, while the achieved elite character makes the distance seem less threatening.”
