In a word, John McCain is exasperated. You can see it when his goes into his puffer-fish look. His chin rises, pushing his mouth up into what would be a pronounced upside-down smile expressing anger, disgust and sadness if it wasn't for the other two aspects of his characteristic look. One of those aspects is that he literally puffs his cheeks out. The second is that he presses his lips together in an expression of anger whose edge is barely softened by the social smile he adds to the look. McCain will say things like, "I'm angry today because..." But one gets the sense that there will always be something new for McCain to be angry about. And why not? In a world needing this much reform, there's always work to be done.
