President Donald Trump has endorsed Texas Attorney General Ken Paxton over incumbent Senator John Cornyn in the May 26 Republican primary runoff, a decision that reshapes the high-stakes race amid growing concerns over Democratic gains in the state. The endorsement comes after weeks of delay, with sources indicating Trump’s frustration over leaked expectations and pressure from his base.
Trump’s Delayed Endorsement Sways Texas Senate Race
President Donald Trump’s endorsement of Ken Paxton in the Texas Republican Senate runoff has injected volatility into a race that was already seen as a potential liability for the GOP. The announcement, confirmed by sources close to the campaign, arrives just days before the May 26 vote, where Paxton and incumbent Senator John Cornyn are vying for the party’s nomination ahead of the November midterms.
The delay in Trump’s endorsement—promised in early March—had left both candidates in limbo, with Cornyn’s team initially expecting support from the former president. However, Trump’s frustration over leaked internal discussions and calls from his most ardent supporters reportedly shifted his stance toward Paxton, a staunch ally in Texas’s conservative base.
Paxton, who has positioned himself as a defender of Trump’s legal and political battles, had publicly offered to withdraw from the race if Cornyn secured Trump’s backing. But with the endorsement now behind him, Paxton’s campaign is framing the moment as a validation of his alignment with the president’s priorities.
Why the Endorsement Matters
Trump’s backing of Paxton over Cornyn—who has served in the Senate since 2002—signals a strategic realignment in Texas politics. Cornyn, a moderate Republican, had been seen as the safer choice to fend off Democratic challenger James Talarico, a state representative who has energized progressive voters. But Trump’s endorsement of Paxton, a more hardline figure, reflects the former president’s influence over the party’s base and his willingness to prioritize loyalty over electoral pragmatism.
Sources told CNN in late April that Trump had grown frustrated after operatives leaked his expected endorsement of Cornyn, prompting him to reconsider. Paxton’s team had also engaged directly with Trump, including a meeting at Mar-a-Lago, where the attorney general emphasized his commitment to Trump’s policy agenda, including the proposed Save America Act
, a sweeping election reform measure.
Cornyn’s campaign, meanwhile, had been bracing for a Trump endorsement, believing it would solidify his standing with conservative voters. The shift to Paxton now forces Cornyn to recalibrate his messaging, particularly as Democrats have gained momentum in Texas, a state that has not elected a Democrat to statewide office since 1994.
The Stakes for Texas and Beyond
The Texas Senate runoff is not just a local contest—it is a litmus test for the GOP’s ability to hold onto key seats in a year when Democrats are eyeing gains in the midterms. With Trump’s endorsement now in Paxton’s corner, the race has taken on national implications, particularly as the former president continues to shape Republican strategy ahead of the 2028 election.
Paxton’s campaign is likely to highlight Trump’s endorsement in advertising, framing it as a seal of approval for his conservative credentials. Cornyn, however, may seek to distance himself from Paxton’s more controversial legal battles, including his ongoing indictments on securities fraud charges, which he has denied.
Analysts note that Trump’s endorsement could also influence other high-profile races, where his backing is seen as a critical factor in mobilizing voters. The decision underscores the enduring power of Trump’s influence within the Republican Party, even as his legal and political challenges continue to dominate headlines.
What Comes Next
With less than a week until the runoff, both campaigns are now in a sprint to solidify their bases. Paxton’s team will likely focus on Trump’s endorsement as a rallying cry, while Cornyn’s campaign may emphasize his experience and moderation as a counterbalance to Paxton’s more divisive image.
The outcome of the runoff will have ripple effects beyond Texas. A Cornyn victory would signal stability for the GOP, while a Paxton win could embolden Trump-aligned candidates in other states. Meanwhile, Democratic strategists are watching closely, knowing that a Republican infight could weaken the party’s chances in November.
For now, the Texas Senate race remains fluid, with Trump’s endorsement serving as the latest twist in a story that has been unfolding for months. The final chapter will be written on May 26, but the political fallout is already being felt across the country.
