Speaking truth to power is the essential responsibiity of the journalist, and it's no less important if it is funny. Satire, when combined with accurate reporting, can be powerful political journalism, which this is. I can't imagine any Comedy Central viewers so unsophisticated that they can't recognize that the cut-up collage of Presidential news clips was created to make a point, even to the point of distorting what the Presidents were trying to say. There is little dispute that eight US Presidents were recorded saying that they would lead the US into energy dependence. At the end, the true enumeration of the environmental policies put into place by Richard Nixon make a point about how far to the right American political zeitgeist has travelled.
