**Republican nominee Brandon Herrera holds a clear edge in Texas's 23rd congressional district for the November 3, 2026, general election.** The seat, a majority-Hispanic border district stretching from western Bexar County through Del Rio and Uvalde toward El Paso, has shifted toward Republicans in recent cycles, reflected in the current 68.5% implied probability for the GOP. Incumbent Republican Tony Gonzales resigned in April 2026 amid scandal, leaving the seat vacant with no special election called. In the March primary, Gonzales finished second to conservative challenger Brandon Herrera (a firearms manufacturer and YouTuber who ran in 2024); Gonzales withdrew before the runoff, handing Herrera the nomination. Democrat Katy Padilla Stout emerged from her primary as the party's nominee. Forecasters including the Cook Political Report, Sabato's Crystal Ball, and others rate the race Likely Republican, citing the district's partisan baseline and limited polling evidence of a competitive contest. An independent candidate is also on the ballot but is not viewed as a major factor. The Republican advantage stems from the district's recent voting trends and the absence of strong Democratic tailwinds seen in some neighboring South Texas seats. Traders price in the structural lean while noting that border issues, turnout among Hispanic voters, and any late national shifts could still influence the outcome before November.
