Sen. John Cornyn has picked up a fresh wave of Texas GOP endorsements as his bruising primary runoff with Attorney General Ken Paxton tightens, and the party is watching nervously because a Democratic pickup would change the Senate math. The contest has turned personal, both camps are stacking endorsements, and national issues like the SAVE America Act are already shaping endorsements and messaging. Voters are weighing Cornyn’s establishment support against Paxton’s grassroots energy while both jockey for President Trump’s eventual nod.
Cornyn announced a slate of 18 new Texas endorsements from prominent Republicans, joining a larger list of state leaders who have publicly lined up behind him. Names like Randy Weber, Nathaniel Moran, Roger Williams, Matt Shaheen and Dade Phelan add to the impression of party unity around the incumbent. That bench of support feeds a clear message: keep this seat in Republican hands.
The race got ugly after neither candidate cleared the 50 percent threshold in the March primary, and both sides have traded sharp attacks ever since. For Republicans, the worry is practical and simple: a loss in November could hand that Senate seat to Democrat James Talarico. Losing a seat would not only be a symbolic blow but a practical wound to the GOP agenda in the upper chamber.
Cornyn responded to the new endorsements by saying “I’m honored to have the endorsement of many longtime friends in Texas politics, whom I have gotten to know during our time in office and with whom I’ve been proud to work.” He reiterated his focus on pragmatic governing and maintaining Republican control in Washington. Those endorsements are presented as proof that party leaders trust his record and electability.
The senator also stressed that he has “always worked hard to earn the trust of our elected officials, so we can roll up our sleeves and work together for the betterment of all Texans.” He added that he looks forward to “continuing our important work together upon my re-election to the United States Senate.” That tone underlines the contrast the campaign wants to draw between steady governance and outsider promise.
Support for Cornyn stretches beyond Texas leaders; he has backing from national Republicans, including Senate leadership and party committees, plus unions and patrol organizations that prioritize border security. Local lawmakers framed their endorsements around energy and security, arguing Cornyn defends Texas interests on national stages. That plays well with conservative voters worried about the economy and the border.
Weber praised Cornyn and said he “has been a tireless fighter for Texas energy, standing up for our oil and gas industry and working to unleash American energy dominance.” He called himself “proud” to support Cornyn “because he will continue fighting to protect our energy producers and keep Texas leading the way.” Those endorsements lean into a familiar Republican playbook: energy, jobs and state pride.
Shaheen warned that the GOP cannot afford losing the Senate seat and wrote, “As someone with a Democrat challenger this November, I understand how vital it is that John Cornyn be our U.S. Senate nominee, otherwise election losses for Republicans could be disastrous.” He noted that Cornyn “has never lost an election,” and argued that “with him at the top of the ballot, he will defeat James Talarico and lift up Republicans in down-ballot races.” The electoral math argument is central to the pro-Cornyn case.
Paxton remains a force with strong grassroots backing and a different coalition of endorsements that highlights conservative activism. He added a recent batch of state-level endorsements and claims a substantial number of Republican leader backers statewide, including allies in Congress and conservative groups. Paxton frames his case around being an America First conservative who will fight for Texas and President Trump.
Paxton declared that “the momentum behind our campaign continues to grow stronger every single day.” He said that “Texans are ready for a change and are ready to be represented by an America First warrior who is going to work tirelessly to help Texas and support President Trump,” adding, “That’s exactly what I’ve done as Attorney General, and it’s what I’ll continue to do as our next United States Senator.” His messaging is direct and aimed at the base voters who want confrontation over compromise.
President Trump’s endorsement remains notably absent, though he has signaled he likes both candidates and hinted his decision will be influenced by the SAVE America Act. Trump said “A lot has to do with the SAVE America Act.” He added, “A lot is going to determine — Republicans have to get that passed, because that will secure voting in this country.” That national policy debate is now part of the Texas runoff calculus.
Cornyn has publicly backed the SAVE Act and wrote about its urgency, arguing for passage even if it requires “whatever changes to Senate rules may prove necessary.” He warned that “the Senate rules will change eventually, whether Republicans like it or not,” and that “this leaves conservatives with two options. We can either unilaterally disarm, or we can stand and fight.” Cornyn doubled down: “We can let the Democrats keep obstructing today and then smash the rules the first chance they get, or we can act now and use the mandate the American people gave this president and this Congress to secure our elections, protect our homeland and bring back common sense,” adding, “The answer is clear: We need to stand, fight and win.”
“Democrats started this fight. Now Republicans should finish it,” said Cornyn, a line meant to rally traditional conservatives around a clear, results-focused agenda. With endorsements piling up on both sides and national issues filtering into local arguments, Texas Republicans are now weighing electability, loyalty and policy in a high-stakes runoff. The outcome will shape not just one Senate seat, but GOP momentum heading into November.
