Incumbent Rep. Roger Williams secured the Republican nomination unopposed in the March 3, 2026, Texas primary for the TX-25 House seat, collecting 100% of 57,938 votes in a district rated Solid Republican by Cook Political Report with an R+18 partisan voter index. Dione Sims won the Democratic primary with 60.5%, but lower turnout and Williams' fundraising edge—$870,000 cash on hand versus Democrats' limited resources—bolster trader consensus at 88.5% for Republicans. The district, spanning Fort Worth suburbs and rural areas where Trump won 68%-31% in 2024, has seen Williams run unopposed in recent cycles, with no polls indicating competitiveness ahead of the November 3 general election.
