 * The piano-playing satirist at the end of the episode is a reference to and . The song "The Deficit Rag" is very similar to Lehrer's "The Vatican Rag".
 * The woman's suffrage display Lisa visits is likely a parody of Susan B. Anthony. When Lisa mentions that "she later appeared on the highly unpopular 75¢ piece", this is likely a reference to the coin, which proved to be very unpopular due to its being easily mistaken for a quarter.
 * It may also be a reference to the, which was issued in the mid-1870s and, like the Susan B. Anthony dollar, was very unpopular due to its too-close resemblance to a quarter.
 * The banner that reads "Brevity is... wit" is a reference to a line in  where says: "brevity is the soul of wit". The joke is that the banner is applying greater wit by increasing the brevity of the original Shakespeare line.

 * During the White House tour, the Simpsons see a sign reading "On this spot, bowled back-to-back 300 games," which Homer scoffs at. In real life, Nixon was an avid bowler; he even frequently bowled while he was President, finding that bowling fit well into his work schedule. However, it's unlikely that he ever bowled back-to-back 300 games.
 * Then-President George H.W. Bush is featured briefly in this episode, and is portrayed in a positive, albeit hokey, light.

Trivia

 * In keeping with the mystery of which state Springfield is in, this episode gives misleading clues. The map shown during the essay reading montage shows Springfield's state as being NT. The junk mail Homer receives shows the state as TA, and an enigmatic 6-digit zip code of 192005.
 * In the office of the congressman from Springfield's state, there is a State Seal. It depicts an ear of corn, a star, a beaver and a nuclear power symbol.
 * Barbara Bush wears a pearl necklace in the bathtub.
 * In Dulles Airport, there is a sign reading "Bus Info" and then a phone number. This was the real phone number of the Simpsons' Art Director, and was drawn there without his knowledge.

Goofs

 * When the lady is asking questions to Homer before Lisa wins the trip to Washington, what she says doesn't match her mouth.
 * When Lisa is reading her speech for the essay contest, what she says does not match her mouth movements.
