In a significant turn of events in Texas politics, state Attorney General Ken Paxton has emerged victorious in the fiercely contested Republican primary for the Senate seat held by incumbent John Cornyn. This victory came after Paxton secured the endorsement of former President Donald Trump, a decision that may have been pivotal in his triumph.

Ken Paxton’s ascent to prominence began with his candid criticism of Cornyn, who has represented Texas in the Senate since 2002. Paxton accused Cornyn of failing to deliver effectively for the Republican Party and the state. He announced his candidacy in April 2025, asserting that Texas needed a senator who would wholeheartedly support Trump and champion Republican values. “We have another great U.S. senator, Ted Cruz, and it’s time we have another great senator that will actually stand up and fight for Republican values,” Paxton proclaimed at the time.
The influence of Donald Trump in the Republican primary cannot be understated. The former president publicly backed Paxton in mid-May, labelling him a “true MAGA Warrior” who would advocate fiercely for Texas in the Senate. Trump’s endorsement highlighted Paxton’s commitment to economic growth and tax cuts, as well as his resilience in the face of challenges, stating that the country needs “Fighters.”
Despite Paxton’s enthusiastic support from the Trump camp, concerns have been raised within Republican circles regarding his appeal in the upcoming general election. Several party members worry that his controversial personal and professional history could jeopardise the party’s chances in November, particularly given that no Democrat has won a U.S. Senate seat in Texas since 1988.
Senate Majority Leader John Thune voiced apprehensions, noting that the potential for a Democratic win is increased depending on their nominee. Cornyn himself reiterated these concerns, emphasising Paxton’s “baggage,” which includes felony securities fraud charges, an FBI investigation for corruption, and impeachment hearings that he ultimately survived. Cornyn argued that Paxton’s problems could damage the Republican Party’s long-standing hold on the seat.
The history of Paxton’s personal life has also been tumultuous, with his wife, Angela Paxton, filing for divorce on “biblical grounds,” accusing him of infidelity. This development has further complicated his standing within the party, raising questions about his ability to unite Republican voters.
Polling data appears to support Cornyn’s concerns. In a memo released earlier this year by the National Republican Senatorial Committee (NRSC), it was indicated that Cornyn would likely prevail in a general election matchup against leading Democratic contenders, while Paxton is projected to struggle. The analysis suggested that while Paxton might narrowly defeat one candidate, he could lose to the other, heightening fears that his nomination could risk flipping the seat to Democrats.
Some of Paxton’s allies have dismissed the notion that he would represent a liability in the general election as a “scare tactic.” Representative Troy Nehls expressed frustration over the argument that voting Paxton risks financial costs for the party in the election. He contended that this approach undermines the confidence voters should have in Paxton’s candidacy.
Another Republican, Representative Wesley Hunt, who also ran for the Senate seat but lagged in polling, accused the NRSC of neglecting the potential complications between Cornyn and Paxton. His spokesperson noted that ignoring early warnings of this internal conflict could have grave consequences for the party’s prospects in maintaining its Senate majority.
Looking ahead, the implications of Paxton’s primary victory raise critical questions for the Republican Party, not only in Texas but also nationally, as party leaders wrestle with the balance between Trump-aligned candidates and traditional Republican values. With the Senate race heating up, the focus will be on whether Paxton can rally support despite his controversies and whether his candidacy can avoid becoming a double-edged sword for Republicans come November.
