President Donald Trump endorsed Ken Paxton in Texas’s Republican Senate runoff, boosting Paxton’s challenge to incumbent John Cornyn. The endorsement drew reactions from both candidates and renewed concern among some Republicans about the general election.
Trump endorsed Paxton on social media ahead of the May 26 runoff against Cornyn, after both advanced from the March primary. Paxton thanked Trump, while Cornyn said the endorsement would affect the race but that his campaign would continue. Cornyn also argued Paxton would be a weak nominee against Democrat James Talarico.
The article describes the runoff as a costly contest and reports that Cornyn-aligned groups had spent substantially more on advertising than Paxton-aligned groups, citing AdImpact. Some Republican senators and leaders expressed concern that Paxton could make the general election harder to win; Sen. Cynthia Lummis said she believed Cornyn had a better chance, and Sen. Tim Scott warned that Republicans might not hold Texas without Cornyn as nominee.
