Incumbent Republican Roger Williams, chair of the House Small Business Committee, secured his party's nomination in the March 3, 2026, primary for Texas's 25th Congressional District, a solidly Republican seat with an R+18 Cook Partisan Voter Index under the new map enacted in 2025 and upheld by the Supreme Court. Trader consensus reflects this structural advantage at 88.5% for the Republican Party, bolstered by Williams' fundraising edge and district demographics favoring GOP turnout in battleground Texas midterms. Democrat Dione Sims, a community organizer and granddaughter of Juneteenth advocate Opal Lee, won her uncontested primary but faces steep historical barriers in safe seats. No polls have emerged since primaries, with the general election set for November 3; national trends or scandals could shift odds.
