What if the joker became mayor of gotham city?

The 2019 film Joker, directed by Todd Phillips, focuses on the character's descent into chaos and the social unrest it inspires in a decaying version of Gotham City. The story does not present the Joker holding any public office, including mayor. Because the available source material does not depict a scenario where the Joker is elected or appointed mayor, we cannot confirm such a role. Any discussion of this premise would be purely speculative and not grounded in the verified content of the film or related canon. Therefore, the idea remains hypothetical with no factual basis in the known sources.
