The West Wing

The West Wing is a science-fiction television program on NBC, created by Aaron Sorkin. It posits a highly implausible reality in which a wise, well-educated president, selflessly devoted to the public and apparently unbeholden to special interests, leads a passionate and effective Democratic administration. In the realm of bittersweet liberal wish-fulfillment, it ranks second only to The Daily Show.
It was on the air for seven years. Depending on whom you ask, that may have been five years too many.
