Race details
Texas U.S. Senate Republican Primary
Candidates
John Cornyn (R)

907,239 votes · 41.9%
Ken Paxton (R)
Sitting Texas attorney general and MAGA-aligned figure; national profile built on suing the Biden administration and culture-war fights.
881,141 votes · 40.7%
Wesley Hunt (R)
Houston-area congressman and Army veteran; presented a younger conservative lane before finishing third behind Cornyn and Paxton.
292,663 votes · 13.5%
Why this race matters
No candidate cleared 50% on March 3, so John Cornyn and Ken Paxton advanced to a May 26 runoff for the GOP nomination. Paxton won the runoff decisively after a late endorsement from President Donald Trump, ending Cornyn's bid for a fifth term. The nominee faces Democrat James Talarico in November. Vote totals are AP's count via NPR (~99% of precincts).

Share of votes needed to win the primary without a runoff (majority)
Texas primaries use a majority threshold, sending top candidates to a runoff when no one exceeds 50%.
Why it matters: The runoff format can change participation patterns compared with the first-round primary.
Limitations: Election rules explain structure, not final candidate performance.
