Senate Majority Leader John Thune — and most of the GOP conference — was reeling Tuesday from President Trump's snap endorsement of Ken Paxton in the Texas GOP Senate runoff.
Why it matters: Thune (R-S.D.) called it Trump's "decision." But it's Thune's problem to pass Trump's agenda, with a trio of senators the president can no longer hurt.
Sen. Thom Tillis (R-N.C.) has been unbowed since announcing his retirement in July 2025 after clashes with Trump.
Sen. Bill Cassidy (R-La.) voted with Democrats Wednesday to advance an Iran war powers vote to debate.
Sen. John Cornyn (R-Texas) has a runoff May 26 but will enter it with Trump backing someone else.
😓 Adding to Thune's degree of difficulty: a president sick of the Senate and its rules, and rank-and-file Republicans seething over Trump's knifing of Cornyn.
"I don't understand. He [Paxton] is an ethically challenged individual," said Sen. Susan Collins (R-Maine).
"I'm supremely disappointed," Sen. Lisa Murkowski (R-Alaska) said.
Driving the news: Trump's endorsement of Paxton came in the middle of his 10-day GOP revenge tour.
"Horrible Congressman Thomas Massie" (R-Ky.), as the president called him, lost his primary Tuesday to the Trump-endorsed Ed Gallrein.
Between the lines: The race will now be "three times more expensive" for Republicans to hold, said Sen. Lindsey Graham (R-S.C.), referencing Democratic nominee James Talarico setting Texas-sized fundraising records.
A Thune ally told Axios: "Republicans may keep Texas, but you broke-it-you-buy-it. MAGA Inc. just became Texas Inc."
What we're watching: The $72 billion reconciliation package will be the first test for the Senate's newly combustible environment.
"I just came off the campaign trail. People love the president," Cassidy said. "But I can tell you, a billion dollars for the ballroom … that's not where their head is, and that's not where my head is."
Zoom out: Trump's relations with the Senate have sunk to new lows overhisfrustration with the Senate parliamentarian, Republicans' refusal to abolish the filibuster, and GOP handwringing over ballroom security funding.
What they're saying: "He's done with the Senate bullsh*t and Thune and all of them. They can't deliver," said a Trump confidante.
"The only reason the president was holding out for Cornyn was the SAVE Act," the confidante said. "And when that became a lost cause, it was 'Why the f*ck should I support this guy?'
"[Trump] saw some polling this weekend.… The polling showed Paxton will win in November. It might have been Paxton's polling. But it's Texas," a Trump adviser said.
⚡️ Zoom in: GOP lawmakers have several must-pass bills in the next five months, followed by several nice-to-pass pieces of legislation.
Trump is demanding money for ICE and Border Patrol before June 1. Section 702 of the Foreign Intelligence Surveillance Act expires June 12. The farm bill needs to pass by Sept. 30.
Republicans are working to pass a housing bill to lower costs and looking for 60 votes on a bill to provide market structure for cryptocurrency.
A reconciliation 3.0 package is still being discussed — with varying degrees of earnestness and snickering — in both chambers.
🙀 The bottom line: Trump has always enforced GOP loyalty with raw fear, naked threats and decisive punishment.
Now he'll learn whether fear loses its hold on lawmakers who have already lost — or are staring at defeat.

Executive Summary
President Trump's endorsement of Ken Paxton in the Texas GOP Senate runoff has created significant tension within the Republican Party, particularly for Senate Majority Leader John Thune. The endorsement, part of Trump's broader "revenge tour," has alienated key senators like Thom Tillis, Bill Cassidy, and John Cornyn, complicating Thune's ability to advance Trump's legislative agenda. Cassidy's recent vote with Democrats on an Iran war powers measure and Cornyn's upcoming runoff without Trump's support highlight the growing divide. Meanwhile, Trump's frustration with the Senate—over issues like the filibuster and ballroom security funding—has further strained relations. The situation is exacerbated by upcoming legislative deadlines, including funding for ICE, the expiration of FISA Section 702, and the farm bill. Republicans are also grappling with internal conflicts over fundraising and policy priorities, as Trump's influence tests the limits of party loyalty.
The political fallout extends beyond the Senate, with Trump's endorsement of Ed Gallrein over Rep. Thomas Massie in Kentucky signaling his continued effort to reshape the GOP in his image. However, the financial and strategic costs of these endorsements—such as increased fundraising challenges in Texas—raise questions about their long-term effectiveness. The reconciliation package and other must-pass bills will serve as early tests of whether the fractured Republican conference can unite under Trump's leadership or if his tactics will further erode party cohesion.
Full Take
The strongest version of this narrative highlights Trump's continued influence over the GOP, even as his tactics create internal fractures. His endorsement of Paxton—despite ethical concerns—demonstrates his prioritization of loyalty over traditional party alliances. The backlash from senators like Collins and Murkowski underscores a growing rift between Trump's base and establishment Republicans, who are increasingly willing to challenge his authority. The financial and strategic costs of these endorsements, such as the Texas runoff becoming more expensive, suggest that Trump's "revenge tour" may weaken the party's electoral prospects.
Pattern scan: The article employs emotional exploitation (ARC-0012) by framing Trump's actions as a "revenge tour," which amplifies conflict and division. There's also an element of false framing (ARC-0043) in presenting the GOP's internal struggles as a binary choice between loyalty to Trump and party unity, ignoring nuanced policy disagreements. The focus on individual senators' reactions without deeper exploration of systemic issues could be seen as evasion (ARC-0031), deflecting from broader questions about the party's future.
Root cause: The paradigm driving this narrative is Trump's transactional approach to politics, where loyalty is rewarded and dissent punished. The unstated assumption is that fear remains the primary tool for enforcing party discipline, but the article suggests this may no longer be effective for lawmakers facing retirement or defeat. Historically, this echoes past intra-party conflicts where ideological purity clashes with pragmatic governance.
Implications: For human agency, this dynamic risks reducing senators to pawns in a loyalty game rather than independent policymakers. The beneficiaries are Trump and his base, while the costs are borne by the GOP's electoral viability and legislative effectiveness. Second-order consequences include potential Democratic gains in competitive races and a further erosion of bipartisan cooperation.
Bridge questions: What would it take for the GOP to reconcile Trump's base with its establishment wing? How might the outcome of the Texas runoff reshape Trump's influence over the party? What alternative strategies could Republicans pursue to unify without relying on fear-based loyalty?
Counterstrike scan: If this were part of a coordinated influence campaign, the playbook would involve amplifying internal GOP divisions to weaken the party ahead of the election. The article's focus on conflict and Trump's disruptive role aligns with this pattern, though it stops short of overt manipulation. The framing is more observational than orchestrated, but the emphasis on discord serves a similar end.
