<p>John Kerry certainly looks like a president--the thick steel-wool hair, the Lincolnian planes and shadows of his face. He is tall and slim and seems serious. He also has the guts to wear salmon-colored ties. A red tie is red and a blue tie is blue, and red and blue know what color they are. Salmon is a more delicate hue. Salmon can't decide what color it is. Sometimes it's pink and sometimes it's orange. It's like wearing ambivalence on your shirt. This is an unusual thing for a politician to do if it's thought through, and it takes courage.</p>
