The Houston-Area Contest Marks A Generational Shift After Redistricting Forced Two Democratic Incumbents Into The Same District.
Rep. Christian Menefee has defeated longtime U.S. Rep. Al Green in the Democratic primary runoff for Texas’ 18th Congressional District, ending one of the most closely watched Houston area congressional races of the 2026 election cycle.
The Associated Press called the race for Menefee after voters returned to the polls Tuesday, May 26, in a runoff created after neither candidate won a majority in the March primary. Menefee led that first round with about 46 percent of the vote, while Green followed with about 44 percent.
The contest was unusual because it placed two Democratic incumbents against each other after Republican led redistricting reshaped the Houston area map and pushed Green out of his longtime political footing. Menefee, 38, had entered Congress earlier this year after winning a special election to replace former Congressman Sylvester Turner, who died in 2025. Before serving in Congress, Menefee was Harris County attorney.
Green, 78, had served in Congress for more than two decades and became one of the most recognizable Democratic critics of President Donald Trump. He repeatedly pushed impeachment efforts and built a national profile around direct opposition to Trump’s administration.
Menefee also campaigned on his record of challenging Trump aligned policies, pointing to lawsuits filed during his time as Harris County attorney. Green leaned on his long record in Congress and framed himself as a proven fighter in Washington.
Menefee’s victory reflects a major generational shift in Texas Democratic politics, particularly in a district with deep historical importance. Texas’ 18th Congressional District has been represented by Black lawmakers for more than 50 years, beginning with Barbara Jordan, the first Black woman from the South elected to Congress.
Outside Spending Became A Major Issue
The runoff also drew national attention because of outside spending. NBC News reported that Menefee benefited from more than $5 million in support from Protect Progress, a super PAC tied to cryptocurrency industry leaders.
Green criticized the role of large donor spending throughout the campaign. Menefee said campaign finance laws should eventually ban super PACs, even as outside support helped shape the race.
The race unfolded during a period of major turnover in Houston congressional leadership. Sheila Jackson Lee died in 2024, Turner died in 2025, and Green’s defeat now closes another long chapter in Houston’s congressional representation.
What Comes Next For Texas’ 18th District
Menefee now moves forward as the Democratic nominee in a heavily Democratic Houston area district. Ballotpedia reports that he is set to face Republican Ronald Whitfield in the November 2026 general election. :contentReference[oaicite:1]{index=1}
For voters in the district, the runoff was more than a contest between two Democrats. It was a decision about experience, generational change and who should carry forward the political legacy of one of Texas’ most historic congressional seats.
