Trump turned an unlevel playing field into a steep cliff
In the long arc of American political realignment, Tuesday's Texas runoffs mark a decisive moment: a sitting senator with decades of institutional standing was undone not by scandal or policy failure, but by a single endorsement delivered six days before the vote. Ken Paxton's victory over John Cornyn reflects how thoroughly the Republican Party has reorganized itself around personal loyalty to Donald Trump, elevating a figure with a turbulent legal history over a seasoned legislator because one man's blessing proved more powerful than millions in establishment spending. The result leaves both parties recalibrating their strategies for November, in a state that has not elected a Democrat to statewide office in over thirty years.
- Trump's last-minute endorsement of Paxton — announced on the eve of early voting — instantly transformed a competitive runoff into a rout, rendering Cornyn's institutional advantages nearly irrelevant.
- The race consumed over $120 million in advertising alone, shattering records and leaving Senate Republicans in the awkward position of having spent heavily against the man they must now fund in the general election.
- Paxton carries serious baggage into November: a securities fraud indictment that was only recently dropped, and a historic impeachment by his own party's supermajority in the Texas House, acquitted by the state Senate.
- Democrats see an opening — Paxton's legal history and the party's financial strain could make Texas more competitive than usual, though no Democrat has won statewide there since 1994.
- Elsewhere in Tuesday's runoffs, Democratic primaries in competitive congressional districts produced their own drama, including a last-minute party intervention to block a candidate whose rhetoric had alarmed House leadership.
The most expensive Senate primary in American history concluded Tuesday night when Ken Paxton, Texas's attorney general, defeated incumbent Senator John Cornyn in a Republican runoff. The outcome turned almost entirely on a single decision: six days before voters went to the polls, President Trump endorsed Paxton, and the race was effectively over. Cornyn had led the March primary and entered the runoff as the establishment favorite, backed by Senate Republican leadership and their fundraising machinery. But Trump's endorsement, long withheld and widely anticipated, proved decisive. As one Rice University political scientist put it, Trump took an already uneven playing field and turned it into a steep cliff.
Paxton's rise is inseparable from his role as one of Trump's most fervent allies. As attorney general since 2014, he led the legal challenge to the 2020 election results in four states — a case the Supreme Court dismissed — and survived a securities fraud indictment and a historic impeachment by the Republican-controlled Texas House, where 121 members voted to remove him on charges including bribery and dereliction of duty. The state Senate acquitted him, and Trump's public support after the trial cemented their bond.
The victory leaves Senate Republicans in a complicated position. They spent millions trying to defeat Paxton during the primary and will now need to spend millions more defending a seat they once considered safe. Majority Leader John Thune, asked whether the endorsement complicated the party's Senate math, offered only that the majority runs through many states. Paxton faces Democrat James Talarico in November — a heavy lift for any Democrat in Texas, though Paxton's legal history may yet become a liability in a general electorate.
Tuesday's balloting extended well beyond the Senate race. In Houston's 18th Congressional District, Democrat Christian Menefee, 38, defeated Al Green, a 78-year-old incumbent displaced by redistricting. In the 35th District, Johnny Garcia won a Democratic primary after the party intervened with a last-minute ad buy to prevent the nomination of a candidate whose inflammatory statements about imprisoning 'American Zionists' had prompted House Democrats to threaten expulsion. Republicans, meanwhile, saw State Senator Mayes Middleton projected to defeat Congressman Chip Roy in the attorney general race, and a railroad commissioner contest drew unusual attention after one candidate's anti-Muslim rhetoric earned rebukes from the state's own governor and lieutenant governor.
The most expensive Senate primary in American history ended Tuesday night with a result that will reshape Texas Republican politics for years to come. Ken Paxton, the state's attorney general, defeated Senator John Cornyn in a GOP runoff that hinged almost entirely on one man's decision made just six days before voters cast their ballots: President Trump's endorsement of Paxton over the incumbent.
Cornyn, first elected to the Senate in 2002 and once the Republican whip, had entered the race as the frontrunner. He finished first in the March primary with a plurality of votes but fell short of the 50 percent threshold needed to avoid a runoff. For months, Trump's position remained unclear. He held a rally in Texas in March without backing either candidate, allowing the deadline for candidates to withdraw to pass. Reports suggested he might even support Cornyn, who had been an ally in his second term despite occasional friction. But on the eve of early voting for the runoff, Trump announced his support for Paxton. The effect was immediate and overwhelming. "The moment Donald Trump endorsed Ken Paxton, he took a somewhat unlevel playing field and turned it into a steep cliff," said Mark Jones, a political science professor at Rice University.
Paxton's path to this moment had been unconventional. As attorney general since 2014, he became one of Trump's most vocal allies, even leading the legal challenge to the 2020 election results in Pennsylvania, Michigan, Georgia, and Wisconsin—a case the Supreme Court dismissed. Yet his tenure has been marked by legal turbulence. He was indicted on securities fraud charges in 2015, which were later dropped in 2024. In 2023, the Republican-controlled Texas House impeached him on charges of bribery, dereliction of duty, and disregard of official duties by a vote of 121 to 23. He was acquitted by the state Senate, and Trump posted a message of support after the trial.
Cornyn's campaign had the backing of Senate Republicans and their fundraising apparatus, which poured millions into opposing Paxton during the primary. The Republican establishment viewed Cornyn as the stronger general election candidate against Democrat James Talarico. But Trump's endorsement upended that calculation. Senate Republicans now face a costly problem: they spent millions defeating Paxton in the primary and will need to spend millions more supporting him in the general election. When asked whether Trump's endorsement would complicate Republican efforts to hold the Senate, Majority Leader John Thune offered a measured response: "The majority runs through a lot of different states."
The race itself was staggering in scale. Combined spending across the March primary and Tuesday's runoff exceeded $120 million in advertising alone, making it the most expensive Senate primary ever conducted. No Democrat has won statewide office in Texas since 1994, making Paxton the heavy favorite in November against Talarico, though the general election will test whether Trump's endorsement translates to a general election victory or whether Paxton's legal history becomes a liability.
Tuesday's runoffs extended beyond the Senate. In the heavily Democratic 18th Congressional District, Democrat Christian Menefee, a 38-year-old who won a special election earlier this year, defeated 78-year-old Al Green, a Trump antagonist who had represented the 9th District since 2005 before redistricting forced him to seek a new seat. In the 35th District, Democrat Johnny Garcia defeated Maureen Galindo, a sex therapist whose calls for imprisoning "American Zionists" prompted House Democrats to threaten expulsion if she won. The Democratic Congressional Campaign Committee intervened with a last-minute ad buy to support Garcia. In the 33rd District, former Representative Colin Allred faced incumbent Julie Johnson in a contentious Democratic primary after redistricting scrambled the political landscape. Republicans also held multiple runoffs for attorney general, railroad commissioner, and congressional seats, with State Senator Mayes Middleton projected to defeat U.S. Representative Chip Roy in the GOP attorney general race. The railroad commissioner race drew particular attention as Chairman Jim Wright faced Bo French, whose inflammatory rhetoric about Muslims and calls for mass deportations drew rebukes even from Governor Greg Abbott and Lieutenant Governor Dan Patrick.

La Conversación del Hearth Otra perspectiva de la historia
Why did Trump's endorsement matter so much when Cornyn had already built such a strong organization?
Because in modern Republican politics, Trump's blessing is a permission structure. Cornyn had money and establishment backing, but Paxton had Trump. That changes how voters see loyalty and authenticity in a way that traditional campaign infrastructure can't match.
Cornyn was actually an ally to Trump in his second term. Why didn't that count for anything?
It didn't matter because Paxton had been loyal first, before Trump's second term even began. Cornyn's support looked transactional by comparison—he'd been at odds with Trump before. In this moment of Republican politics, early loyalty is what gets rewarded.
The Republican Senate campaign arm spent millions opposing Paxton in the primary, then has to spend millions supporting him in the general. That seems like a strategic disaster.
It is. But they had no choice. They thought Cornyn was the safer bet, and they were probably right on the merits. But once Trump moved, the party had to move with him. The cost is real, and it will matter if the Senate comes down to a handful of seats.
What does Paxton's legal history—the impeachment, the indictment—mean for the general election?
That's the open question. In a state where no Democrat has won statewide office in 26 years, it might not matter much. But Talarico will certainly try to make it central. Whether voters care depends on whether Trump's endorsement inoculates Paxton or whether the baggage becomes too heavy.
The railroad commissioner race seems almost absurd—French calling for mass deportations and questioning whether Muslims or Jews are a bigger threat.
It is absurd, and it's telling that even Abbott and Patrick, who are hardly moderates, found him beyond the pale. But he's still competitive because he appeals to a certain slice of the Republican base. That's the state of play in Texas right now.
