Omaha made history on Tuesday by electing the city’s first Black mayor and by doing so ended more than a decade of Republican control of Nebraska’s largest city.

Douglas County, Neb., Treasurer John Ewing Jr. (D) ousted Republican Omaha Mayor Jean Stothert, the city’s first female mayor who was seeking a record fourth term.

Although the mayor’s office is nonpartisan, the candidates made it clear to voters that Stothert is a Republican and Ewing is a Democrat.

The race initially focused on local issues, but it became nationalized in the final stages as Stothert ran ads criticizing Ewing for supporting transgender athletes and gender-affirming care for minors.

Ewing fired back with ads tying Stothert to Trump, showing the mayor on a split screen with the president and saying, “Let’s say no to the chaos and elect a mayor who will actually get things done,” The Associated Press reports.

At her election night event, Stothert said she called Ewing and conceded in the race, according to KETV.

“I called John Ewing, and I congratulated him,” Stothert said. “John Ewing is inheriting tonight a great city, and we leave a strong foundation for the city that we love. We are grateful and we are hopeful.”
