The race to become the Republican nominee in Texas’ upcoming Senate election is coming to a head.

After failing to secure more than 50 percent of the vote during Tuesday’s primary race, incumbent Sen. John Cornyn will face off against Texas Attorney General Ken Paxton in a May runoff election to determine who will represent the Grand Old Party on the state’s 2026 ticket. While President Trump declined to make an endorsement in the contest prior to this week, it appears the president is now changing his tune.

Trump issued a Truth Social post on Wednesday saying that the primary race “cannot, for the good of the Party, and our Country, itself, be allowed to go on any longer.” He further revealed that he “will be making [his] Endorsement soon, and will be asking the candidate that [he doesn’t] Endorse to immediately DROP OUT OF THE RACE!”

Reports emerged in the hours that followed indicating that the president is preparing to endorse Cornyn, a move that puts him at odds with a sizeable portion of his base, who generally favor the MAGA-aligned Paxton.

While Cornyn has attempted to posture himself as aligned with Trump and conservative causes throughout his 2026 reelection campaign, a look at the senator’s record indicates that he has often sided with the interests of the GOP establishment.

When President Biden and his party pushed for a major gun control package in 2022, all Senate Republicans like Cornyn had to do was say, “No.” But Texas’ senior senator had other ideas.

The Republican primary in Texas’ Senate race is headed to a May runoff between incumbent John Cornyn and Attorney General Ken Paxton after neither secured a majority, with President Trump shifting from silence to preparing an endorsement likely favoring Cornyn, despite Paxton’s strong MAGA backing. Trump’s warning for the loser to drop out underscores the high stakes, as Cornyn tries to court Trump-aligned voters but has a record that often aligns with GOP establishment interests, such as breaking ranks on key issues like 2022 gun control legislation, highlighting deep divisions within the party ahead of the 2026 race.
