BREAKING: Ken Paxton ROUTS John Cornyn In Texas Senate Showdown…

Texas Attorney General Ken Paxton routed four-term incumbent Senator John Cornyn in Tuesday’s Republican Senate primary runoff, delivering one of the most decisive and consequential results of the 2026 midterm cycle.

With 230 of the state’s 254 counties reporting by 9 p.m. Tuesday — just two hours after polls closed — Paxton had captured 63.4% of nearly 903,000 votes cast. The margin was not close. It was a statement.

“Tonight we just sent a Texas-sized message to Washington,” a jubilant Paxton declared before a roaring crowd in Plano. “I said it in March and I’ll say it again now. Today, change was on the ballot. Change won.”

The victory marks a stunning end to the Senate career of one of the longest-serving and most institutionally powerful Republicans in Texas history. Cornyn, first elected to the Senate in 2002, will leave office in January — the first Republican senator from Texas to be defeated in a primary since Lloyd Bentsen beat Ralph Yarborough in a previous era of Texas politics.

The race had been building toward this moment for months, ever since Paxton launched his challenge by declaring on Fox News that it was time for Texas to “have another great senator that will actually stand up and fight for Republican values, fight for the values of the people of Texas and also support Donald Trump.” His entry immediately reframed the contest as a referendum on loyalty, energy, and the direction of the Republican Party itself.

The primary contest first went to voters on March 3rd, when neither candidate cleared the 50% threshold required to avoid a runoff. Cornyn edged Paxton in the first round — 42% to 41% — with U.S. Rep. Wesley Hunt pulling 13% in a distant third. The narrow margin kept Cornyn’s campaign alive but foreshadowed a brutal sprint to the finish.

That sprint turned into a rout once President Donald Trump weighed in. Just one week before Election Day, Trump issued a late but earth-shaking endorsement of Paxton, describing him as “a true MAGA warrior” and throwing the full weight of his political brand behind the attorney general. The endorsement sent shockwaves through the Republican-controlled Senate, which had spent months and millions in resources attempting to shore up Cornyn.

Paxton himself wasted no time crediting the man who made the difference. “I’ve never seen an endorsement matter more since I’ve been paying attention to politics,” Paxton said on The Clay Travis & Buck Sexton Show on Election Day. He later called Trump’s endorsement “the most powerful force in politics” — and Tuesday’s results gave him every reason to believe it.

Senate Republican leadership had worked aggressively to prevent exactly this outcome. Senate Majority Leader John Thune and NRSC Chair Tim Scott had both urged Trump to back Cornyn, arguing he was the party’s safest option for holding the seat in the general election. The Republican establishment poured resources into Cornyn’s effort — pro-Cornyn groups outspent Paxton’s campaign and allied super PACs by a margin of $16.5 million to $5.9 million since the March primary. None of it was enough.

Rep. Wesley Hunt, who had finished third in March and held the spoiler role that forced the runoff in the first place, threw his support behind Paxton the same week Trump issued his endorsement — a symbolic closing of ranks around the challenger that left Cornyn politically isolated in the race’s final days.

For Cornyn, the loss is a deeply personal one. He has served Texas with distinction since 2002, holding the position of Senate Republican Whip from 2013 to 2019 and narrowly losing a bid to lead the Senate Republican Conference to Thune in 2024. His voting record throughout his tenure was almost perfectly aligned with President Trump’s agenda — a fact that his supporters argued should have insulated him from a MAGA-fueled primary challenge.

But in the Republican Party of 2026, a strong voting record alone is no longer sufficient armor. Cornyn stayed neutral during the 2016 GOP presidential primary, and in 2023 told reporters that Trump’s political time had “passed him by” — remarks that would prove impossible to fully walk back regardless of subsequent demonstrations of loyalty.

Paxton’s path to Tuesday’s victory was not without turbulence. The attorney general was impeached in 2023 by a GOP-controlled Texas House on bribery and corruption charges, before being acquitted by the state Senate. He also faces a long-standing securities fraud indictment. Last year, his wife filed for divorce, citing what she described as “biblical grounds.” His opponents made these controversies the centerpiece of a relentless negative advertising campaign.

Cornyn’s campaign never let up on the attacks. Ads hit Paxton over his office’s handling of a Waco sex abuse case, his legal troubles, and what they described as a pattern of ethical failures and mismanagement. One ad flatly declared: “Crooked Ken Paxton is Funding the Left.” Despite the barrage, Republican primary voters rendered their verdict clearly and decisively.

Political analysts took note of what the lopsided result revealed. “Paxton — for all his baggage, for all the things he suffered from, including an impeachment — he somehow got through this thing,” said Jon Taylor, chair of the Department of Political Science and Geography at the University of Texas at San Antonio. It is a testament to the enduring strength of Trump’s endorsement and the grassroots hunger for fighters over institutionalists.

Paxton’s victory is the latest in a series of successful Trump interventions in Republican primaries this cycle. The President has made it a deliberate priority to reshape the Senate GOP caucus in his image, and Tuesday’s result is his most consequential victory to date — toppling a four-term incumbent with deep establishment roots and national standing in the party.

The win sets up what promises to be a fiercely contested general election matchup. Paxton will face Democratic state Representative James Talarico in November — a candidate who won his own primary convincingly and has been barnstorming the state under a “Take Back Texas” banner. Talarico defeated U.S. Rep. Jasmine Crockett in the Democratic runoff, 53% to 46%, in a race of his own.

National Republicans, including Senate leadership, had long argued that Paxton’s baggage made him a riskier general election candidate than Cornyn. Some allies of Thune privately worried that the Texas seat — which Trump carried by 14 points in 2024 — could be put in play by Paxton’s controversies, potentially forcing the party to divert resources from other competitive Senate races.

Supporters of Paxton and Trump dismiss those concerns, pointing to the fundamental strength of the Republican brand in Texas and arguing that a fighter with a proven conservative record is always preferable to an establishment incumbent who delivers lukewarm loyalty when it counts most.

The spending disparity throughout the campaign was staggering. Cornyn and his allied groups had waged a monthslong advertising campaign, largely negative, investing tens of millions against the attorney general. Yet the dollar advantage proved no match for the Trump endorsement and the organic energy behind Paxton’s grassroots coalition, which dominated among self-identified conservatives, MAGA voters, high-propensity primary voters, and even seniors in pre-election polling.

For the broader Republican Party, Tuesday’s result carries a simple and unambiguous lesson: incumbency, institutional support, and a favorable voting record mean nothing if a candidate has, at any point, shown insufficient devotion to the movement that now defines the GOP. Cornyn’s 24-year career ends not in defeat at the hands of Democrats, but at the hands of the party he has served his entire career.

Paxton, for his part, heads into the general election with momentum, a powerful presidential endorsement behind him, and a mandate from the Texas Republican base. The November race against Talarico will command national attention and significant resources from both parties. But on this night in Plano, none of that was on Paxton’s mind.

“The people are on our side,” he had said back in March. Tuesday’s results proved him right — overwhelmingly so.
