June 2, 2026 – Dr. David J. Horn has announced his candidacy for Mayor of Decatur. Horn has served on the Decatur City Council since May 2017.
Horn stated he has been a resident-centered city council member focused on improving where we live and enhancing quality of life for all. He says his priorities as Mayor will include public safety, job creation, neighborhood revitalization, and reversing population decline.
Horn says he voted against increasing property taxes and voted no to unnecessary spending, voted against more gambling establishments in the city and is opposed to carbon sequestration under Lake Decatur. Horn was also a supporter of a cannabis dispensary.
Councilman Horn received the 2023 Advocate of the Year award from the Macon County Continuum of Care. One of the nominators wrote “Councilman David Horn is a standup citizen and does not back down from doing what is right for those without a voice.” Another wrote: “He is not afraid to stand up for an unpopular viewpoint when it has the city’s residents’ best interests at heart.”
