Texas Attorney General Ken Paxton (R-TX) defeated incumbent Senator John Cornyn (R-TX) in the Republican primary runoff on May 28, 2024 [1, 2].
The victory signals a shift in the Texas GOP, demonstrating the significant influence of Donald Trump's endorsement on primary voters in the state.
Paxton's win marks a rare defeat for an incumbent senator in a primary runoff [1, 3]. The race concluded with Paxton securing the nomination for the U.S. Senate seat, effectively ending Cornyn's tenure in that role [2, 3].
Observers said that a last-minute endorsement from President Donald Trump played a critical role in Paxton's momentum [1, 4]. This support helped Paxton consolidate voter preference among the Republican base, which has increasingly aligned with Trump's political priorities over the last several years [3, 4].
Cornyn had campaigned on his experience and established record in the Senate [2]. However, Paxton's alignment with the current direction of the national Republican party proved more appealing to the runoff electorate [1, 4].
The results were confirmed following the Tuesday vote in Texas [2, 3]. Paxton now moves forward as the presumptive Republican nominee for the general election, while Cornyn faces a political exit from the Senate [1, 3].

This result underscores the continued dominance of Donald Trump's endorsement within the Republican primary process. By toppling a long-term incumbent like Cornyn, Paxton has demonstrated that loyalty to the Trump-aligned wing of the party now outweighs seniority and institutional experience in Texas GOP politics.
