Prediction markets give a 42% probability to: will john cornyn win the 2026 texas republican primary? — # Cornyn is looking to Congressman Hunt and President Trump for support against Paxton.
U.S. Senator John Cornyn is actively courting key Republican figures, including President Donald Trump and supporters of Houston Congressman Wesley Hunt, as he faces a formidable primary challenge from Texas Attorney General Ken Paxton. The runoff election is set for May 26, 2026, with the winner advancing to face Democratic nominee James Talarico in the general election. Cornyn has publicly framed the race as a choice between his record and a "corrupt public figure," directly targeting Paxton's legal entanglements. [CBS News, Mar 29]
Paxton's campaign has gained momentum within the party's activist base, as evidenced by his reception at the Conservative Political Action Conference (CPAC), where Cornyn was notably absent and booed by the crowd. Paxton has successfully painted the incumbent as insufficiently loyal to Trump's agenda, a narrative Cornyn's allies counter by noting his 99.3% voting record with the former president. The high-stakes intraparty clash has led other prominent Texas Republicans, like Senator Ted Cruz, to declare neutrality, refusing to endorse either candidate publicly. [The New York Times, Mar 29]
The divisive primary is seen as potentially jeopardizing Republican control of the Senate, with Democrats viewing the 2026 midterms as a prime opportunity to win a statewide race in Texas. The contest has sparked debate over the state's runoff system, with some opinion pieces advocating for ranked-choice voting to avoid similarly costly and bitter battles in the future. All attention is now focused on the final weeks of campaigning ahead of the late-May runoff, which will determine the GOP's standard-bearer in a critical Senate race. [Houston Chronicle, Mar 31]
