What Happened
Texas Attorney General Ken Paxton defeated four-term incumbent U.S. Senator John Cornyn in the Republican primary runoff election on Tuesday, May 26, 2026. The Associated Press (AP) called the race for Paxton one hour after polls closed. With 59% of votes counted, Paxton held 63.2% of the vote to Cornyn's 36.8%. The contest followed a March 3 primary where Cornyn led but did not win a majority. Former President Donald Trump endorsed Paxton on May 19, 2026, during the second day of early voting, and reaffirmed his support on May 24 via social media.
Why this Matters to You
This primary result may signal a shift in the direction of the Republican Party in Texas, potentially affecting the types of policies and candidates that gain prominence at the national level. As the nominee, Paxton's legal history and the party's internal divisions could become central issues in the general election campaign. For Texas voters, the November election will now feature a contest between Paxton and Democrat James Talarico, who was nominated in March. A Democrat has not won a statewide office in Texas since 1994, which suggests the Republican nominee is likely favored in the general election.
What's Next
Paxton will face Democratic state Representative James Talarico in the November general election. The general election campaign is likely to focus on Paxton's record as attorney general, which includes criminal indictments, whistleblower allegations, and an impeachment trial in 2023 from which he was acquitted. The intense and expensive primary fight may present a challenge for Republican unity heading into the fall. A political science professor noted that 'the stain of the fight has left a lasting problem for unity among Republicans.'
