Ken Paxton took 63.8 percent of the vote in the Texas Republican runoff on May 26, 2026. John Cornyn took 36.2. A margin of roughly 28 points ended a Senate career that began in 2002 and made Cornyn the first Republican senator from Texas ever to lose renomination.
The way he spent the final day is the entry.
His pinned post going into the runoff was a photograph of himself standing beside Donald Trump. He spent the day amplifying material disputing the charge that he had been disloyal, and material noting that he had voted yes on every major Trump law. That last claim was true. His voting record was almost perfectly aligned with the president’s agenda, and everyone including his opponent knew it.
So the closing argument of a twenty-four-year Senate career was not a record of legislation, or a case about Texas, or anything he believed. It was a defense against an accusation of insufficient obedience, delivered by a man who had in fact been obedient, to voters who had been told obedience was the only qualification that counted.
They did not believe him. He lost by 28.
What he was actually guilty of.
The charge sheet against Cornyn has two items, and they are worth examining because of how small they are.
The first is from 2022. After the Uvalde school shooting, in which nineteen children and two teachers were killed in his own state, Cornyn negotiated a bipartisan gun package with Democrats. Trump condemned it publicly, naming Cornyn and calling him a RINO, and predicted it would be remembered as the first step toward confiscation.
The second is from May 18, 2023. Speaking to Texas reporters, Cornyn said the party needed an alternative for 2024 and that Trump’s time had passed him by.
The content of that remark matters enormously.
He framed the entire objection as electability. He said it came down to whether a candidate could win, that there is no prize for coming in second, and that Trump did not appear to understand that a general election requires appeal beyond a base. He did not say Trump was unfit. He did not raise January 6, or the documents, or the conduct that had by then produced multiple indictments. He raised the polls.
This is a tactical argument made by a former chairman of the party’s Senate campaign committee, whose profession was counting votes, in the ordinary language of a man doing his job. It contains no moral content whatsoever.
Trump responded by mocking him by name alongside Mitt Romney and giving him a nickname.
That is the offense. A gun bill after a massacre of children in his own state, and a poll-based observation about electability, offered once, in 2023.
