2004 was an election year, so it was unreasonable for the audience to assume it could escape having to see at least one political commercial.
The political commercial that Couch Potato has the misfortune of seeing is a commercial for Louie Dewey (John Paul Buttermore), senatorial candidate and brother of Huey Dewey the lawyer and Chewey Dewey the used-car salesman.
Louie Dewey is the candidate for everyone! No matter what you believe in, he agrees with you! No matter what position you take or what platform you support, he is in favor of it! You can't go wrong with Louie Dewey!
Poor Couch Potato is about to gag at the retched commercial, when he is mercifully saved by a call from Dumpling in the kitchen: supper is ready. However, Lawrence Welk reruns are just coming on, so he leaves the TV on so he and Dumpling can hear the music while they eat. As he wends his way from the living room, the room lights come up for intermission.
