There's one wrinkle I see here, speaking as an Aaron Sorkin fanboy.
There's a lot Sorkin does that just shouldn't work. His dialogue is extremely lengthy and, in the case of The West Wing and Sports Night, he completely threw out the idea of using internal (team) conflict to drive the narrative, choosing unity instead. His President of the United States was extraordinarily idealistic and principled, even under fire.
This is a long way of saying I think Sorkin does it this way to amuse himself. He creates things he, himself, would like. He certainly feels an obligation to his audience, as the parent comment mentioned, but overall he writes the characters and dialogue in a way that gives him pleasure.
edit: Even going so far as to inject the idea of taking pleasure from writing things well into his scribe characters: Danny and Casey in Sports Night, Toby, Sam, President Bartlet and Will on the West Wing.
