Chris Gober (R) defeated Jessica Karlsruher (R), Scott MacLeod (R), and seven other candidates in the Republican primary for Texas' 10th Congressional District on March 3, 2026. The filing deadline was December 8, 2025. As of January 2026, Gober, Karlsruher, and MacLeod led in local media attention.

Incumbent Michael McCaul (R), first elected in 2004, did not run for re-election, saying he was "looking now for a new challenge." McCaul endorsed Gober on January 12, 2026.

Gober was, as of the election, an attorney and the chief executive officer of Lex Politica, which Gober described as "the nation’s top conservative law practice, consistently winning for conservatives in the toughest legal and political battles of our time." Gober earlier worked for the U.S. Department of Justice, the Republican Party, and America PAC. Gober said he was running "because President Trump needs allies who know how to beat the Left and won’t back down."
