Krusty runs for Congress when The Simpsons protest against airplanes flying over their house.

!! Tropes:

* UsefulNotes/RMSTitanic: The congressman who died early in the episode, Horace Wilcox, is stated to have been a ''Titanic'' survivor.
* ShoutOut:
** The title is an allusion to ''Film/MrSmithGoesToWashington''. Both the film and this episode feature an election to find a replacement for a senator who dies before the end of his term.
** Mayor Quimby regrets building his shrill-voiced girlfriend an opera house, which was done in ''Film/CitizenKane''.
* YourMom: Krusty accidentally does this when he makes a speech to Latin-American voters--he says, "I'm going to vomit on your mother's grave," without realizing what it meant. Upon being informed by a translator, Krusty understands why his maid quit on him.
