The Runoff Contest
Incumbent Republican Sen. John Cornyn and Texas Attorney General Ken Paxton will meet in a May 26 runoff to decide the GOP nominee for the U.S. Senate seat. The winner will face Democrat James Talarico and Libertarian Ted Brown in November.
Background & Context
Paxton faces a felony securities-fraud indictment, a 2023 impeachment on bribery and abuse-of-office charges, and a public divorce. Cornyn, a four-term senator, emphasizes his record while courting the MAGA base. No Trump endorsement was secured.
Key Figures
John Cornyn, incumbent senator; Ken Paxton, attorney general; James Talarico, Democratic state rep and primary winner.
Data & Statistics
TSU poll (April 22–May 6) shows favorability: Talarico 46 %, Paxton 42 %, Cornyn 37 %; unfavorable: Talarico 35 %, Paxton 48 %, Cornyn 49 %. In November matchups, Talarico trails Cornyn 44-45 % and ties Paxton 45-45 % (8 % undecided). Fundraising: Cornyn >$70 M, Paxton $16 M, Talarico $40 M (+$9 M super-PAC).
Why It Matters
The seat decides Senate control. Paxton may be vulnerable to Democrats; Cornyn’s support could preserve GOP dominance. The race also exposes establishment-MAGA tensions and voter fatigue.
Official Statements & Responses
Cornyn’s campaign stresses Trump alignment and critiques Paxton’s ethics via a Mother’s Day ad. Paxton’s ads call Cornyn a “milquetoast” and cite a 2016 “naive” border-wall comment. Talarico backs a gasoline-tax cut.
Criticism & Opposition
Paxton’s conduct is spotlighted in a Mother’s Day ad that asks Texas mothers whether they would want their daughters to marry a man like Paxton. GOP strategists warn declining enthusiasm may lower turnout.
Conflicting Reports & Gaps
A University of Houston poll shows Paxton leading Cornyn 48 %–45 %, but the 2.8-point margin of error makes the true lead uncertain. No public Trump endorsement adds ambiguity to the electoral impact.

What’s Next
