Where are the Biden jokes? Why haven't they tackled the diary or laptop? That speech with the red background, calling half the country terrorists? The Bidens are a walking Jerry Springer episode and they haven't done anything with them, as far as I know.

When you see how much vitriol South Park issued toward Trump (even though Parker and Stone said they wouldn't do any Trump jokes) and compare it to how it ignored or softballed every other president in the show's lifetime (alongside everyone else you listed), you start to realize how it may have been controlled opposition, if not neocon propaganda from the start.
