The point is that television does not reveal who the best man is. In fact, television makes impossible the determination of who is better than whom, if we mean by 'better' such things as more capable in negotiation, more imaginative in executive skill, more knowledgeable about international affairs, more understanding of the interrelations of economic systems, and so on. The reason has, almost entirely, to do with 'image.' But not because politicians are preoccupied with presenting themselves in the best possible light. After all, who isn't? It is a rare and deeply disturbed person who does not wish to project a favorable image. But television gives image a bad name. For on television the politician does not so much offer the audience an image of himself, as offer himself as an image of the audience. And therein lies one of the most powerful influences of the television commercial on political discourse.
