Texas Republican voters handed Attorney General Ken Paxton a commanding victory over incumbent Sen. John Cornyn in Tuesday's Senate runoff, and the senators who spent months propping up Cornyn wasted no time pretending they'd been on Paxton's side all along.
The margin was not close. Paxton defeated the four-term senator by roughly 28 percentage points, a result so lopsided it left no room for the usual post-primary hedging. Within hours, Senate Majority Leader John Thune, Senate Majority Whip John Barrasso, and Sen. Tim Scott, all of whom had publicly backed Cornyn, issued endorsements of Paxton and turned their fire on Democratic nominee James Talarico.
The speed of the pivot tells a familiar story about Washington's permanent class: loyalty to voters runs a distant second to loyalty to the majority count. Republican leadership wanted Cornyn. Texas Republicans wanted Paxton. And the moment the numbers came in, leadership got in line, after months of working against the man they now call essential to the party's future.
The Daily Caller News Foundation reported the whiplash in detail. Back in March, after neither candidate cleared the threshold in the initial primary, Thune called Cornyn "one of the most effective and respected conservative leaders" in the nation. Barrasso "fully" supported Cornyn over Paxton. Scott praised Cornyn as a party warrior.
By Wednesday morning, Thune was on The Hugh Hewitt Show singing a different tune entirely. He told listeners:
"The Republican voters in Texas spoke last night, Ken Paxton is our nominee for November and we've got to pivot and go all in to make sure that we keep Texas red, that he wins, and that we keep a far-left liberal out of the United States Senate. And obviously that seat is going to be very key to our majority which will determine the future of this country."
"Pivot" is one word for it. Another might be capitulation.
Barrasso posted his endorsement on X even faster, on May 27, the night of the runoff itself. He called a vote for Paxton "a vote for a safer, stronger, and more prosperous America" and labeled Talarico "a far-left extremist" and "a rubber stamp for open borders, illegal immigrant criminals, and men playing in women's sports."
That language is strong. It's also language Barrasso could have used weeks ago, had he been willing to accept what Republican primary voters were telling him.
Perhaps the most revealing detail is what happened at the National Republican Senatorial Committee, chaired by Scott. The NRSC had scrubbed anti-Paxton attack posts the day after his victory. One deleted post had criticized Paxton's extramarital affair. A July 2025 statement headlined "Ken Paxton's Lies and Incompetence Keep Piling Up" now returns a 404 error on the committee's website.
The committee that called Paxton incompetent last summer now needs him to hold a Senate seat. So the receipts vanish.
This is not a minor housekeeping matter. The NRSC exists to elect Republican senators. When it spends resources attacking a Republican who wins the nomination anyway, it hands opposition researchers free ammunition. Deleting the posts doesn't erase the record, it just confirms that leadership knows how bad the contradiction looks.
President Trump endorsed Paxton just one week before the runoff, and the effect was decisive. Fox News reported the contest was the most expensive Senate primary in history, yet Cornyn's institutional advantages could not overcome the late Trump endorsement. Paxton himself acknowledged the weight of the moment, saying, "When everyone in Washington told him to abandon me and abandon the people of Texas, he didn't listen. Instead, President Trump gave me his complete and total endorsement."
The Newsmax tally put Paxton at approximately 62.5 percent of the vote. The New York Post reported the final margin at 63.8 percent to 36.2 percent, a 27-point gap. Either way, this was not a squeaker that leadership can explain away as a fluke.
Cornyn, a senator since 2002 who once held a GOP leadership post, struggled to overcome conservative dissatisfaction over his record on Ukraine aid, bipartisan negotiations, and gun safety legislation. The Washington Times noted that Cornyn had opposed Trump's border wall proposal a decade ago and was slow to back Trump's 2024 presidential run, liabilities that compounded over time with a base that rewards loyalty and punishes hedging.
Cornyn conceded and pledged to support Paxton: "I've said throughout this race that I trust the voters of Texas, and they've made their decision, and I respect it."
Ohio Sen. Bernie Moreno appeared to be the first senator to endorse Paxton, doing so moments after the Associated Press called the race. Moreno's statement was the most colorful of the bunch, calling Talarico "Beto 2.0" and "a far left freak who supports open borders, trans ideology, and even called the American flag a 'complicated symbol.'" He added: "Make no mistake: Ken Paxton will beat him in November and crush the dreams of the out-of-state billionaires propping up his campaign."
Scott, who chairs the committee that had been attacking Paxton for nearly a year, tried to split the difference. His X post praised Cornyn as a warrior before adding: "But now I stand united with President Trump, Ken Paxton, and Texans who want to protect our Republican Majority. Talarico is a disaster and Texans will have nothing to do with his absurd agenda in November."
The word "but" in that statement does a lot of heavy lifting.
Ted Cruz, Texas's senior senator, remained neutral throughout the primary process, a choice that now looks strategically shrewd. Cruz is set to host a $3,500-per-person fundraiser for Paxton on June 2, positioning himself as a unifier rather than a convert.
Paxton's victory is not an isolated case. It follows primary defeats of Sen. Bill Cassidy and Rep. Thomas Massie, both of whom ran afoul of Trump and paid for it at the ballot box. The pattern is consistent: Republican incumbents who break with the base on high-profile issues find themselves vulnerable, and a Trump endorsement of their challenger can turn vulnerability into a rout.
Senate leadership has now watched this happen multiple times. Each time, the establishment candidate loses. Each time, leadership endorses the winner within hours. And each time, the prior months of institutional opposition get memory-holed.
The question Republican voters should ask is simple: if Paxton is good enough to endorse on Wednesday, why was he too flawed to support on Monday? The NRSC's deleted attack posts, Thune's glowing praise of Cornyn, Barrasso's "full" support for the incumbent, none of that has been retracted or explained. It's just been overwritten.
Democrats, for their part, appeared cautiously optimistic about facing Paxton in November. That optimism may prove misplaced in a state as red as Texas, but it was fed in part by the very attacks that Republican leadership itself authored and has now erased.
The general election will test whether Talarico, whom Republicans have framed as a radical on borders, gender ideology, and patriotism, can compete in a state Trump carried twice. The broader pattern of party leadership capitulation suggests that the establishment's concerns about electability will matter far less than the base's demand for alignment.
There is nothing wrong with endorsing the party's nominee after a primary. That is how elections work. The winner gets the support of the team. What makes this episode worth watching is not the endorsement, it's the velocity of the reversal and the effort to erase the evidence of opposition.
Republican voters in Texas made a clear choice. They chose the candidate who fought the Biden administration in court, who carried Trump's endorsement, and who ran as an outsider against a 24-year incumbent. They did so by a margin that left no ambiguity.
Leadership's job now is to help Paxton win in November. But voters have every right to remember that the same leaders who call Paxton indispensable today were calling him unfit less than a year ago, and hoping nobody would notice the difference.
Washington always finds a way to land on the winning side. The trick is pretending you were there all along.
