Incumbent Daniel Crenshaw (R), Steve Toth (R), and four others are running in the Republican primary for Texas' 2nd Congressional District on March 3, 2026. The filing deadline is December 8, 2025. As of November 2025, Crenshaw and Toth led in fundraising and local media attention.

The Texas Tribune's Gabby Birenbaum described Toth as "aligned with the rightmost faction of the Texas Legislature...by far the best-known primary opponent Crenshaw has faced in his career." Jameson Ellis (R) challenged Crenshaw in the 2022 and 2024 primaries, losing to Crenshaw 75%–17% in 2022 and 60%–40% in 2024.

FOX News' Peter Pinedo says Crenshaw has "emerged as a prominent Republican lawmaker and outspoken conservative voice but has also taken criticism from some on the right, such as Toth, who have accused him of being too establishment." Referencing Crenshaw's past statements supporting aid to Ukraine and criticizing some Republicans, Toth said he was running because the district "deserve[s] an unwavering conservative who will fight for our convictions and never bend the knee to the radical left." A Crenshaw spokesman said Crenshaw "has been fighting — and winning — to secure the border, fight against radical transgender ideology and deliver crucial flood mitigation to Texas' 2nd Congressional District since he's been in office."

Crenshaw was elected to the House in 2018. A veteran of the U.S. Navy, Crenshaw says he stands for "common sense policies that ensure our nation’s prosperity and security, represent our Foundational values, and give Texans a reason to once again be proud of their leaders." Crenshaw says he is "running for re-election because Texas isn't done fighting and neither am I."

Toth was elected to the Texas House of Representatives in 2012. He ran unsuccessfully for state Senate in 2014 and U.S. House in 2016 before being re-elected to the state House in 2018. Toth says he is running because Crenshaw "ran as a conservative but has done nothing except act like the newest version of Liz Cheney in Congress."

Also running in the primary are Martin Etwop (R), T.C. Manning (R), Nicholas Plumb (R), and Ava Zolari (R).

If no candidate receives more than 50% of the vote, the top two finishers will advance to a runoff on May 26.
