Exactly. South Park reflects the perspective of two people who realize that corruption, demagoguery, bad thinking, and cowardice isn't limited to one party, and that politics isn't just a matter of "you're either with me or against me".

Both the Left and the Right are in a hell of sorts this election year. Neither candidate is reflective of the actual views held by either group, they are not transformative in their politics, they are greedy, and they aren't genuine in any way. In short, what both sides deserve.
