The White House Comment Line Is a Vicarious Thrill for the Audience

This is an analogue to the present day. These days, alex pretends that every important person in the world listens to his shows. The audience gets to feel vicarious excitement of pretending that alex is talking directly to and telling truth to power. In two thousand nine alex couldn't really pretend that anyone in power cared all that much about what he was doing. This is the same kind of risk Alex wants to pretend he's taking by faking leaving a voice mail for the white house.
