 Because I have not been president. This is not to detract from President Johnson at all, but he has had to make the tough decisions, Mr. Spivak. It is President Johnson that has had to call the shots, so to speak, that has had to face up to the responsibilities of the management of our affairs. The vice president of the United States does not do that. I knew when I became vice president that we only had one president at a time, that I ought not to act like the president, nor should I try to pretend that I'm president.
