President Trump has officially thrown his weight behind Texas Attorney General Ken Paxton to unseat incumbent Senator John Cornyn in the Texas primary, sending shockwaves through GOP ranks. According to The Hill, this aggressive strategy of targeting fellow lawmakers who have either defied or criticized him is creating a palpable sense of anxiety.
Trump successfully rallied supporters to defeat Senator Bill Cassidy in Louisiana, and he also ousted Rep Thomas Massie from his seat in Kentucky’s 4th Congressional District. These wins are clear signals that Trump’s influence over the primary electorate remains incredibly potent. It has led many seasoned Republicans to worry about the potential for massive political backfire and the long-term cost.
Senator Thom Tillis (R- NC) was clear about the fallout. “Why are you creating a structural vote count that could prevent you from getting almost anything done with a supermajority going forward?” Tillis asked, noting that Trump’s beefs with GOP senators could make it very tough to get 60 votes to pass legislative priorities through the upper chamber. “Why would anybody think that that makes sense? I count votes,” he said.
His concern is that Trump is alienating established GOP members
This will make sure it’s nearly impossible to pass controversial or unpopular legislation. As Tillis pointed out, “I hope to God that John Cornyn wins next week, but if he loses, [the president’s] got a structural five or six votes [in the Senate GOP conference] that can stop anything from a simple majority for the remainder of his term,” he warned.
When you look at why Trump is targeting Cornyn, the reasons are deeply petty. Per the BBC, Trump took to Truth Social to say, “John Cornyn is a good man, and I worked well with him, but he was not supportive of me when times were tough.”
This frustration stems from the fact that Cornyn, despite his long history as a party loyalist and his role in the Senate leadership from 2012 to 2024, didn’t endorse Trump’s re-election bid until January 2024. That delay, which lasted more than a year after Trump entered the race, clearly didn’t sit well with the president.
In contrast, Trump is backing Ken Paxton, a politician who has been a vocal and close ally. Paxton has backed Trump’s efforts to overturn the 2020 election results and even traveled to New York City to rally for him during his recent trial. Trump himself seems to view Paxton as a reliable fighter, stating on Truth Social, “I know Ken well, have seen him tested at the highest and most difficult levels, and he is a winner!”
Yet, Paxton is a controversial figure, even within his own party, as he comes with plenty of baggage. He has faced a federal corruption indictment that he recently settled, and he was impeached by the Texas legislature in 2023 for alleged fraud and obstruction of justice, though he was later acquitted in a state Senate trial.
Some Republicans, like Senator Susan Collins, have labeled him “ethically challenged,” and Senator Lisa Murkowski expressed that she was “supremely disappointed” by the endorsement. Despite this, Cornyn is trying to stay focused, telling the media that he has the “best team and the best plan” and intends to win.
The frustration among other GOP members is mounting. Senator Lisa Murkowski noted that Trump’s endorsement makes things harder for the entire Republican team. “It’s supposed to be something where you’re trying to work with one another, not against your own team, and it just kind of felt like he was working against his own team,” she said.
Senate Majority Leader John Thune also weighed in, warning that the path forward is getting complicated. “There’s always a consequence associated with taking on incumbent United States senators,” Thune told reporters.
The Hill reports that there’s another layer to this tension: many of the lawmakers Trump is targeting are still in office for another seven months. Now that they have been marked for removal, they no longer have the political incentive to play nice.
In fact, they are likely to feel more emboldened to push back against key legislation. This is a significant issue because, in a narrowly divided Congress, just a few GOP defections can derail an entire party-line bill.
We are already seeing this with Senator Bill Cassidy, who recently joined Democrats in advancing a war powers resolution to limit Trump’s military action in Iran. Representative Thomas Massie, on the other hand, has criticized the administration’s plans for a new White House ballroom even after his defeat.
As Republicans look toward a busy legislative calendar, this internal friction threatens to derail their ability to deliver results.
