Disgust is the single most characteristic emotional state that "America's Mayor" shows on his face. When Giuliani speaks, the upper lip on the left side of his face will often curl slightly upward, revealing what appears to be an aversion to whatever person, idea or event he may be discussing. Giuliani is often derisive and dismissive of rivals, particularly Democrats, and his raised lip signals, in effect, that the opposition stinks. Meanwhile, the natural resting position that Giuliani's mouth sits in when he's not talking is for the corners of the mouth to turn down in a form of disgust verging on bitterness. In meet-and-greet situations, he tends to look down and away from people. The bottom line: the former Mayor of New York City is combative, bringing a prosecutor's mentality to politics.
