5/28/2026, 1:40:42 AM
Core Event
On May 26 2026 Texas Republican voters chose Attorney General Ken Paxton over four-term incumbent Senator John Cornyn in the party’s Senate primary runoff. Paxton secured roughly 64 % of the vote to Cornyn’s 36 %, a margin of about 28 percentage points.
Background & Context
The contest followed a March 3 primary in which neither candidate achieved a majority, prompting a runoff. President Donald Trump entered the race a week before voting began, endorsing Paxton after weeks of speculation. The endorsement came amid a broader pattern of Trump-backed challenges that have unseated incumbents in Indiana, Kentucky and Louisiana.
Key Figures & Groups
- Ken Paxton – Texas Attorney General, MAGA-aligned, previously impeached by the Texas House (2023) and acquitted by the Senate; faced a securities-fraud indictment resolved with a $300,000 restitution payment; divorced on “biblical grounds.”
- John Cornyn – Four-term U.S. Senator, former Senate whip, longtime Texas political figure; voted with Trump 99 % of the time, posted reading *The Art of the Deal*, and proposed naming a highway after the president.
- Donald Trump – Former president, wielded his endorsement as a decisive factor; described Paxton a “true MAGA warrior” and labeled Cornyn “very disloyal.”
- Republican leadership – Senate Majority Leader John Thune, NRSC chair Tim Scott, and other GOP leaders publicly supported Cornyn while warning that Paxton’s candidacy could endanger the party’s Senate seat.

Why It Matters / Impact
Texas provides a 53-47 Republican Senate majority. Analysts warn that a Paxton nomination could force the GOP to divert hundreds of millions of dollars to defend the seat, potentially weakening campaigns in other battleground states. The result also underscores Trump’s continued ability to shape GOP nominations, raising questions about the party’s electability versus loyalty to the former president.

- Cornyn conceded, stating, “I’ve always supported the Republican ticket. I intend to do so again in this general election.”
- Republican leaders (Thune, Scott) expressed concern that Paxton’s “scandal-plagued” profile could jeopardize the seat but pledged continued support for the party’s nominees.
- Democratic leaders (Chuck Schumer, Kirsten Gillibrand) hailed the outcome as a step toward flipping the Senate.
Criticism & Opposition
Republican strategist David Urban warned that Trump’s “cavalier” approach makes the November midterms “tough” for the party. Senate Republicans John Thune and Tim Scott warned that Paxton’s controversies could cost the GOP the seat. Former Senator Jeff Flake called the intra-party battle “painful to watch.” Democratic analysts noted Paxton’s legal and ethical baggage as a liability in the general election.
