The Trump Paxton endorsement has sharply raised the stakes in the Texas Senate runoff, giving Texas Attorney General Ken Paxton a major boost against incumbent Republican Sen. John Cornyn.
President Donald Trump endorsed Paxton on Tuesday, May 19, 2026, one week before the Tuesday, May 26, 2026, Republican runoff for the U.S. Senate seat in Texas. The decision adds new momentum to Paxton’s campaign as he tries to unseat Cornyn, a four-term senator and longtime Republican figure in Washington.
Why Trump’s Backing Matters in the Texas GOP Race
Trump praised Paxton as a loyal MAGA supporter and said he would continue delivering for Texas in the Senate. The endorsement was announced as Paxton supporters gathered at a campaign event in Allen, Texas, where the news was met with celebration.
Paxton and Cornyn advanced to the runoff after the Tuesday, March 3, 2026, primary, when no candidate won a majority. Rep. Wesley Hunt finished third and did not move forward.
Cornyn has supported much of Trump’s agenda in Washington, but Paxton has framed himself as the stronger Trump-aligned conservative in the race. That contrast has made the runoff a larger test of whether Texas Republican voters prefer an establishment incumbent or a more combative MAGA-backed challenger.
Cornyn Faces Electability Questions Before May 26 Vote
Trump’s endorsement also puts pressure on Republican leaders who see Cornyn as the safer nominee for the November general election. Cornyn has warned that Paxton could make the race more difficult for Republicans because of his past controversies.
Paxton was acquitted in a 2023 impeachment trial on corruption charges and reached a deal in 2024 to end a long-running securities fraud case. Those issues are expected to remain part of the Democratic argument if Paxton wins the nomination.
Democrats Watch Texas Race Closely
Texas State Rep. James Talarico is the Democratic nominee for the seat. He has framed the general election as a fight against wealthy donors and what he describes as a corrupt political system.
The Texas Senate runoff is now one of the most closely watched Republican contests of the 2026 election cycle. Trump’s late endorsement may give Paxton a decisive edge with conservative primary voters, while also setting up a broader November fight over electability, party loyalty and the future direction of Texas politics.
