Tim O'Hare will be on the November ballot for Tarrant County Judge, overcoming challenger Betsy Price for the Republican nomination.
O'Hare secured 57% of votes while Price had 34%.
Results came in during the 4 a.m. hour after being delayed overnight due to an equipment malfunction, Tarrant County Judge Glen Whitley said.
Whitley had announced last summer he would not seek a fifth term, leading to seven candidates coming forward hoping to lead the Tarrant County Commissioners Court.
Price's 10 years as mayor of Fort Worth made her the longest-serving mayor in the city's history before she, too, announced her retirement from the office last year.
O'Hare, a former Farmers Branch mayor and former Tarrant County Republican Party Chair also brought the recommendation of former President Donald Trump.
On the Democratic side, Deborah Peoples secured the party nomination against Marvin Sutton, taking 83% percent of votes against Sutton's 17%.
Peoples, the former chair of the Tarrant County Democratic Party, ran to replace Price as Fort Worth mayor but lost in a runoff on June 5, 2021, to Mattie Parker. Peoples also challenged Price for mayor in 2019 and lost by 14%.
Sutton is an Air Force veteran and a former air traffic controller who served on the Arlington City Council and most recently ran for Arlington mayor.
