House
Congressman Michael McCaul (R-Austin)
Over the weekend during a television interview, Rep. McCaul announced that he would not seek a 12th term in the House. He was originally elected in 2004 and rose to chair two full committees, the Committee on Homeland Security and House Foreign Affairs.
McCaul served his full term-limited allotment of six years heading the Homeland Security Committee. Though he chaired the Foreign Affairs panel for only two years, he was the Ranking Minority Member for the previous four. Under Republican House Conference rules, the combined position of Chairman and Ranking Member cannot exceed six years.
Congressman McCaul had been thought of as a potential Texas statewide candidate over the years but never launched such a campaign. He now plans to pursue interests outside of elective politics when his current congressional term ends at the beginning of 2027.
The combined retirement announcements of Reps. Luttrell and McCaul mean that at least seven of Texas’ 38 congressional seats will be open for the 2026 election. Rep. Lloyd Doggett (D-Austin) is retiring, assuming the new Texas map survives legal challenges, and Rep. Chip Roy (R-Austin) is running for state Attorney General. The Houston-anchored 18th District is vacant due to the death of Rep. Sylvester Turner (D). The new redistricting map created three new open seats, Districts 32 and 33 centered in Dallas County and District 35, anchored in San Antonio.
Overall, the McCaul retirement announcement moves the national open House seat count to 32, including 18 Republican held seats, 11 Democratic, and the three new Texas map districts. Though the open list is expanding, the general election competition within these districts remains light. Still, only two opens, MI-10 (Rep. John James-R) and NE-2 (Rep. Don Bacon-R), can be ranked in the toss-up category. Competitive primaries, however, will occur in all congressional openings.
The open-seat list will soon recede to 29 once special elections are held in Arizona (7th District; Sept. 23), Tennessee (7th District; Oct. 7 special primary; Dec. 2 special general election), and Texas (18th District; Nov. 4 jungle primary; runoff to be scheduled after it becomes clear that no one receives majority support in the initial vote).
The new TX-10 District begins in western Travis County, where McCaul resides, and then moves through a strip in northern Travis where it connects to the rest of the district. Moving east, the new 10th annexes 10 whole counties and part of Warren County all located east of Waco and north of the Houston metro area. Included within this group is Brazos County, which houses Texas A&M University.
We can expect a crowded 10th District Republican primary with the winner claiming the seat in November of 2026. The new 10th is rated safely Republican. President Trump carried the region over Kamala Harris with a 60-38 percent margin according to calculations from The Down Ballot political blog statisticians.
The Texas candidate filing deadline is Dec. 8 for the March 3, 2026, Lone Star State primary. Should no candidate secure a majority in the initial election, which is likely for all of the state’s seven open congressional seats, a runoff contest between the top two finishers is scheduled for May 26, 2026.
