American Narcissus | The Weekly Standard: "People have been noticing Obama’s vanity for a long time. In 2008, one of his Harvard Law classmates, the entertainment lawyer Jackie Fuchs, explained what Obama was like during his school days: “One of our classmates once famously noted that you could judge just how pretentious someone’s remarks in class were by how high they ranked on the ‘Obamanometer,’ a term that lasted far longer than our time at law school. Obama didn’t just share in class—he pontificated. He knew better than everyone else in the room, including the teachers. ”"
