Paxton defeats Cornyn in Texas Republican Senate primary
The result marks a significant shift in Texas Republican politics, with the Attorney General unseating the long-serving Senator in the party’s primary contest.
Texas Attorney General Ken Paxton has defeated incumbent Senator John Cornyn in the Republican primary for the US Senate seat. The outcome confirms a shift in the state’s political landscape, ending Cornyn’s tenure in the upper chamber.
The defeat follows a public endorsement from US President Donald Trump, which was issued in the week preceding the election. The President explicitly backed Paxton over Cornyn, a move that appeared to influence the final result in the closely watched contest.
Paxton, currently serving as the state’s top law enforcement officer, successfully challenged the sitting Senator. Cornyn, who had held the seat since 2002, was unable to retain his position against the former Attorney General’s campaign.
The primary election results were reported on 26 May 2026. The timing of the presidential endorsement, released just days before the vote, underscored the influence of the White House in shaping the party’s internal dynamics ahead of the general election.
While the source material does not provide specific vote counts or the margin of victory, the confirmation of Paxton’s win signals a decisive break from the previous leadership within the Texas Republican delegation. The result will likely have broader implications for the party’s strategy in upcoming federal races.
The outcome stands in contrast to broader market reactions to recent geopolitical developments, including a summit between President Trump and Chinese President Xi Jinping in Beijing. That summit, focused on trade and artificial intelligence, had previously prompted positive responses in US stock markets, though it remains distinct from the domestic political shift in Texas.
