HOUSTON — Political turnout driven by high-profile congressional races in Houston’s 18th District influenced results in the Democratic primary runoff for Harris County judge, political observers said Wednesday after former Houston City Council member Letitia Plummer defeated former Houston Mayor Annise Parker.
Plummer received 51.1% of the vote, while Parker received 48.9%, according to unofficial results. Plummer will face Republican nominee Orlando Sanchez in November after Sanchez defeated Warren Howell in the GOP primary runoff.
Political science professor Michael O. Adams of Texas Southern University said turnout tied to the Democratic runoff in Texas’ 18th Congressional District likely affected down-ballot results, including the county judge race. Plummer placed first in the March primary with 46.6% of the vote.
The Democratic runoff in CD-18 between U.S. Reps. Christian Menefee and Al Green drew significant attention in the Houston area, Adams said. Menefee won the race with 69.4% of the vote.
Adams said higher participation in that contest likely benefited Plummer.
Former Harris County Judge Ed Emmett, a Republican, also said turnout patterns linked to the CD-18 race influenced the county judge results, noting that Democratic runoff participation was concentrated in the district.
Adams said Plummer also benefited from broader Democratic turnout patterns in urban Harris County races, including other down-ballot contests.
He cited victories by Darrell Jordan Jr. in the Democratic runoff for district clerk and Melanie Miles in the race for Justice of the Peace, Precinct 7, Place 2, as part of the same electoral environment.
Emmett said Plummer’s path to victory reflected stronger-than-expected turnout dynamics in Democratic runoff voting and suggested Republicans face broader electoral challenges in Harris County in the upcoming general election.
Plummer said during a Wednesday news conference that voters were seeking new leadership and change in local government.
She said voters wanted candidates who are not longtime incumbents and who can bring new ideas to county leadership.
Adams said turnout trends in Houston-area Democratic races could also affect November’s general election, including the Texas Senate race between state Rep. James Talarico and Attorney General Ken Paxton.
He said Black voter participation in Democratic primaries remains a key factor in statewide and local outcomes.
