Polling shows a volatile GOP Senate primary in Texas, with Ken Paxton holding an early edge over Sen. John Cornyn and President Donald Trump’s looming endorsement poised to reshape the race as it heads toward a May 26 contest.

A fresh survey from Texas Public Opinion Research found Ken Paxton outpacing incumbent Sen. John Cornyn, and the results make clear how much hinge rests on a possible endorsement from President Donald Trump. President Donald Trump has signaled that an endorsement in the race may be coming soon, and that he would prefer that whoever he doesn’t select drop out from the race. That kind of pick could compress the field quickly and force a choice for Republican voters across the state.

The poll shows Paxton leading Cornyn by eight points in the current matchup, a gap that looks meaningful but still sits within a competitive window. If Trump were to endorse Cornyn, the survey finds Paxton would slim to a one point lead, with 13 percent of potential GOP voters still undecided. The poll claims a margin of error of about four percent.

Flip the endorsement and the landscape shifts dramatically: should Trump back Paxton, Paxton would hold a 16 point advantage heading into the May 26 primary, according to the same figures. Those scenarios make the president’s signal more than theater — his choice could determine whether the incumbent survives or is overtaken. For activists and donors, an endorsement would be a clear cue on where to put time and money.

Paxton has indicated willingness to negotiate along the lines President Trump suggested, including a contingent offer tied to moving legislation. Paxton has indicated that, per Trump’s suggestion, he would be willing to drop out of the race should the Senate suspend the silent filibuster in order to pass the SAVE America Act, an election integrity bill championed by Trump and the vast majority of Republicans. That kind of bargaining shows how campaign strategy is merging with policy priorities this cycle.

Cornyn’s answer has been to push back on some of those ideas while signaling he will fight for what he sees as procedural tools to advance conservative goals. Cornyn said that he would be willing to implement the talking filibuster to pass Trump’s legislative agenda in response to Paxton’s suggestion of a deal. It’s a reminder that even within the same party, tactics over Senate rules can become fuel for primary attacks and voter debate.

The winner of this bruising primary will face a Democratic opponent in November who’s already drawing national attention, sharpening the stakes for Republicans who want to hold the seat. Whoever comes out the victor in the heated race will take on the radical James Talarico in the general election in November. For GOP voters in Texas, the choice is not just about November but about what kind of conservative message the party takes to the electorate.

Beyond endorsements, turnout and undecided voters will decide the outcome, and that 13 percent figure matters as much as the headline numbers. With roughly a month until the primary, campaigns will press hard to convert those undecideds into committed supporters and to motivate the reliable base. Expect ad spending, ground game pushes, and intensified media appearances as both sides race to lock in votes.

Polls capture a snapshot, not the whole picture, so both candidates will try to make the snapshot work for their narrative while preparing for the next move. Even with Paxton’s reported lead, the margin of error means there’s room for surprises and late swings, especially if the president’s endorsement lands on one candidate. That uncertainty will keep this matchup in the national spotlight until ballots are cast.

For Republicans watching closely, the Texas primary will be an early test of whether national influence and policy tradeoffs can tilt a statewide race. The May 26 date is fast approaching, and whoever claims the Republican nomination will need to consolidate support quickly to defeat a motivated Democratic challenger in November. Expect conservative groups, donors, and voters to measure their options against both electability and principle as the contest tightens.

Editor’s Note: The 2026 Midterms will determine the fate of President Trump’s America First agenda. Republicans must maintain control of both chambers of Congress.
