A Texas congressman’s personal scandal has scrambled one of the most competitive House races in the country — and now Donald Trump has stepped in to pick a side.
In the weeks following the March 3, 2026 Republican primary for Texas’ 23rd Congressional District, the race has undergone a dramatic reshaping. Incumbent Rep. Tony Gonzales — a moderate Republican first elected in 2020 — advanced to a May 26 runoff against gun rights activist Brandon Herrera, only to find himself engulfed in controversy over an alleged affair with a congressional aide who later died by suicide. Then came the endorsement that changed everything.
Trump, who had previously backed Gonzales, switched his support to Herrera. “Brandon Herrera has my Complete and Total Endorsement to be the next Representative from Texas’ 23rd Congressional District — HE WILL NEVER LET YOU DOWN!” the former president declared, all but anointing Herrera as the presumptive GOP nominee heading into the runoff.
A Rematch With Very Different Stakes
This isn’t the first time these two have faced each other. In the 2024 Republican runoff for the same seat, Gonzales held off Herrera by a razor-thin margin — 50.6% to 49.4%. Roughly 400 votes separated them. Herrera, who built a national following through his popular YouTube channel centered on firearms and Second Amendment advocacy, never really went away. He came back harder, and this time the numbers reflect it.
In the March primary, Herrera edged out Gonzales among four candidates — pulling 43% of the vote to Gonzales’ 42%, a spread of roughly 900 votes out of more than 55,000 cast. Neither cleared the majority threshold needed to avoid a runoff, but the message was unmistakable: the congressman’s grip on his own district is slipping.
Still, Gonzales didn’t sound like a man ready to fold. On primary night, he struck a defiant tone, thanking supporters and saying, “Thank you President Trump and all those TX23 constituents that support our campaign. Onward to a victorious May.” That was before Trump pulled the endorsement. The “victorious May” he envisioned now looks considerably harder to reach.
The District, The Demographics, The Stakes
Texas’ 23rd is no ordinary House seat. It stretches 800 miles along the U.S.-Mexico border, covers a vast swath of West Texas, and is 67% Hispanic — a demographic reality that’s always made it one of the more unusual Republican-held districts in the country. Gonzales, who speaks Spanish and has worked across the aisle on immigration issues, had positioned himself as the kind of moderate who could hold a purple-ish district in a sea of red. That brand is now under significant strain.
On the Democratic side, Katy Padilla Stout won the party’s nomination and will face whichever Republican survives the May 26 runoff. Democrats, who have been eyeing the 23rd for years, are surely watching the GOP implosion with considerable interest.
Herrera Makes His Pitch
How does Herrera frame what’s happening? Simply: voters want integrity. “I think that a lot of people are looking for the office to have the same sort of integrity that it always needed to, and not only that, but somebody who actually represents the conservative voice of a very conservative district,” he told reporters after the primary results came in.
It’s a clean message, and in the current climate, it lands. Herrera has long argued that Gonzales isn’t conservative enough — pointing to votes the congressman cast that drew criticism from the right. Now, with the personal scandal layered on top of the ideological critique, Herrera has more ammunition than he’s ever had. And a Trump endorsement to boot.
Gonzales, for his part, has not announced a withdrawal from the race. Whether he can survive through May — politically, personally, and reputationally — remains the central question hanging over one of Texas’ most watched congressional contests. The controversy surrounding the alleged affair has intensified calls from some Republicans for him to step aside entirely, though as of now he appears to be pressing forward.
That’s the catch. Even with Trump’s blessing now firmly behind Herrera, a sitting congressman doesn’t disappear just because the political winds shift. Gonzales has won before under pressure, in a district where name recognition and incumbency still count for something. But this time, the weight bearing down on him is different in kind — not just a challenger with good polling, but a personal cloud that campaigns can’t easily spin away.
The May 26 runoff will decide whether a scandal-weakened incumbent can somehow hold on, or whether a YouTube-famous gun activist with the most powerful endorsement in Republican politics will flip the seat and send a very different kind of Republican to Washington.
Either way, the 23rd Congressional District — all 800 border miles of it — isn’t done making news.
