He's not the first 18-year-old mayor in US history, but that hasn't stopped his family celebrating the major win.The new mayor ran on a platform of improving the police force, repairing the city's drainage system, addressing abandoned houses and improving community involvement.While in high school, he served as president of the school's student government association, and had leadership roles in school clubs.He received advice during his campaign from the mayor of the city of Little Rock, Arkansas, which has a population of over 200,000."I'm proud of his willingness to enter into public service at such a young age and his aspirational goals for the City.""
