A veteran Republican senator who was just driven from office by President Donald Trump’s political machine is now warning that the president may soon regret it.
Sen. John Cornyn (R-Texas), who lost his Republican Senate primary runoff to Trump-backed Texas Attorney General Ken Paxton, is predicting that Republicans could face major trouble in the 2026 midterm elections — and that Trump himself will suffer the consequences.
In an interview with The New York Times, Cornyn said he believes the president is setting himself up for what could become “the most miserable two years of his life” if Republicans lose ground in Congress next November.
“I think November is going to be a disaster,” Cornyn told the newspaper. “He’s going to have the most miserable two years of his life in the last two years of his term.”
The warning comes just weeks after Paxton delivered a crushing defeat to Cornyn in the Texas GOP runoff, ending the senator’s more than two-decade Senate career. Trump endorsed Paxton late in the race, helping push the controversial attorney general to victory over one of the most senior Republicans in Washington.
Cornyn admitted he believed Trump might stay neutral in the contest.
“I had really thought that we’d gone on so long with no endorsement that he was just going to stay out of it,” Cornyn told the Times. “But he couldn’t resist.”
The outgoing senator also suggested Trump’s treatment of him revealed a broader problem inside today’s Republican Party.
“If he would do that to me, he would do that to anybody,” Cornyn said. “There’s never going to be good enough for him, other than 100 percent, slavish adherence to whatever he wants.”
Cornyn argued that such demands run counter to the constitutional role of senators, who are supposed to provide checks and balances rather than unquestioning loyalty to any president.
The comments mark one of the sharpest public rebukes Trump has received from a longtime Republican ally. Despite occasional disagreements, Cornyn voted with Trump’s agenda at an exceptionally high rate during the president’s first term and was widely viewed as part of Senate Republican leadership’s institutional wing.
Trump nevertheless sided with Paxton, whom he praised as a loyal supporter of both himself and the MAGA movement. Following the runoff, Trump wrote on Truth Social that Cornyn would remain his friend and that Republicans would soon see Paxton become “a fantastic, common sense Senator.”
Cornyn was not impressed.
“If that’s the way friends treat you, you wonder about his enemies,” he remarked.
A Growing Republican Concern
Cornyn’s warning reflects concerns that have quietly surfaced among some Republicans since Paxton’s victory.
Several GOP senators and strategists argued before the runoff that replacing Cornyn with Paxton could complicate Republican efforts to hold the seat in November. Paxton carries years of political baggage, including impeachment proceedings in Texas and numerous ethics controversies that Democrats are expected to spotlight during the general election campaign.
According to reporting from Semafor, some Republican senators privately worried that Trump’s endorsement would make the Texas race significantly more expensive and difficult to defend, forcing the GOP to divert resources from other key battlegrounds.
TIME magazine similarly reported that establishment Republicans viewed Cornyn as a safer candidate and feared Trump’s intervention could create an opening for Democrats in a state that has remained reliably Republican for decades.
ABC News noted that Cornyn’s loss joins a growing list of Republican officials whose conservative credentials proved insufficient after falling out of favor with Trump.
Looking Ahead To 2026
Cornyn’s prediction comes as both parties begin looking toward the 2026 midterms, when control of Congress will once again be on the line.
Historically, the president’s party often loses seats during midterm elections, particularly during a second term. Should Republicans suffer significant losses in either chamber, Trump could find himself facing congressional investigations, legislative gridlock, and renewed political battles during the final two years of his presidency.
For now, however, Trump’s grip on the Republican base remains strong enough to reshape the party even against the wishes of many of its elected leaders.
Cornyn’s defeat may ultimately become one of the clearest examples yet of that reality.
The question now is whether his warning about a coming Republican “disaster” proves prophetic — or whether Trump’s political dominance continues carrying the GOP through another election cycle.
