Politics is a common theme in the animated sitcom The Simpsons, and this phenomenon has had some crossover with real American politics. The local politics of the fictional town Springfield feature prominently in many episodes, and character archetypes represent different political concepts within a community. The show satirizes ideas across the political spectrum, though overall it is described as having left-wing and anti-establishment bias. Politicians have been caricatured in many episodes of The Simpsons, including an episode following President George H. W. Bush in response to his public criticism of the show. References to the show also feature in real-world politics. The Simpsons addresses contemporary issues including substance abuse, the economy, education, environmentalism, gun politics, health politics, LGBT rights, immigration, and criminal justice. Episodes of the show have also caused international political dispute for its portrayal of foreign countries.
