Cornyn draws contrast with Massie, Cassidy days before election
Senator John Cornyn is working to distance his reelection campaign from previous high-profile Republican primary upsets, arguing that his upcoming runoff on Tuesday against Texas Attorney General Ken Paxton is fundamentally different.
The race was reshaped last week when President Donald Trump endorsed Paxton, noting that Cornyn was “late in backing me” during his latest presidential run. The endorsement has provided a substantial boost to the attorney general, elevating his standing in public polling and prediction markets, while underscoring Trump’s enduring influence in GOP primaries.
Distinguishing the Texas Race
On Sunday, Cornyn rejected comparisons to Republican lawmakers like Representative Thomas Massie and Senator Bill Cassidy, both of whom faced successful primary challenges after clashing with Trump. Massie drew the president’s ire by opposing the war in Iran and pushing for transparency regarding the Jeffrey Epstein files, while Cassidy voted to convict Trump during his second impeachment trial following the January 6, 2021, attack on the U.S. Capitol.
Cornyn maintained that his legislative record reflects consistent support for the administration’s agenda.
“I think it’s very different from the Cassidy and Massie situation, because I’ve been a Trump ally,” the Republican lawmaker said Sunday on NewsNation’s The Hill Sunday.
Cornyn suggested that Trump’s endorsement of Paxton was born out of frustrations rather than a fundamental policy divide, describing Trump as “an impatient guy” who “got frustrated with the Senate” when unable to secure his priorities quickly. Cornyn noted that the endorsement was an attempt to “send a message,” adding that he has supported Trump’s agenda while choosing his disagreements on a case-by-case basis.
High Stakes for November
The May 26 Republican runoff was triggered after neither candidate secured a majority in the initial March primary. The winner will face Democratic state Representative James Talarico in the November general election. Recent polls and prediction markets suggest Talarico is within striking distance of flipping Texas, a state Democrats haven’t carried for statewide office since 1994.
The runoff has emerged as the most expensive Senate primary runoff in U.S. history, with combined campaign advertising spending soaring past $120 million. It pits Cornyn—a four-term incumbent backed by GOP leadership—against the outspoken Paxton, a Trump-aligned challenger who has embraced a more confrontational political style and who supported Trump’s efforts to overturn the 2020 election results.
The race is widely seen as a test of whether Republican voters favor establishment experience or a more populist approach, with potential implications for the direction of the party nationally. Cornyn is attempting to frame his race less as a referendum on loyalty and more as a question of electability, warning that nominating Paxton could put a typically safe Republican Senate seat at risk in the general election.
Support From GOP Leaders
Cornyn has continued to draw support from Republican leaders in Washington, with members of the Senate GOP and establishment-aligned groups backing his bid for reelection. That support reflects concerns among some Republicans that Paxton—who has faced legal and ethical scrutiny—could be a riskier nominee in November.
Senate Majority Leader John Thune expressed his disappointment with Trump’s endorsement, reiterating his support for Cornyn, whom he called a “principled conservative” while speaking to reporters on Tuesday.
Senator Susan Collins of Maine said the president picking Paxton left her dismayed, adding, “John Cornyn is an outstanding senator and deserved, in my judgment, the president’s support.
Senator Lisa Murkowski of Alaska said that she was “supremely disappointed” by Trump’s move and feared it put the Texas seat “in jeopardy.”
Senators James Lankford of Oklahoma and Thom Tillis of North Carolina have also publicly backed Cornyn.
The final days of the race are expected to center on turnout among Republican voters, with both campaigns focusing on mobilizing their respective bases in what is typically a lower-participation runoff. The result could hinge on whether Cornyn’s support among more traditional Republicans outweighs Paxton’s appeal to highly motivated conservative voters.
