John Cornyn lost his bid for a fifth term in the Senate on May 26, 2026, after being defeated by Ken Paxton in the Texas Republican primary runoff. Megyn Kelly of The Megyn Kelly Show framed the outcome as a "huge win for Paxton," noting the scale of the incumbent's exit.
The loss marks a dramatic end to a long-standing political career. Michael Barbaro on The Daily highlighted that John Cornyn was a "four-term Republican who had not faced a close general election in his more than 20 years in the Senate." The Global News Podcast noted the lopsided spending, stating it was a "stunning defeat for a man who has served in Congress for close to a quarter of a century," despite the establishment spending nearly $100 million on his behalf.
Commentary remains divided on whether Donald Trump was the primary catalyst. While the Global News Podcast attributes the upset to Donald Trump having "lobbed a missile into the middle of all of that by endorsing an opponent with a "controversial record," others are looking toward the general election. The Megyn Kelly Show points to a fractured party, with guests noting that many John Cornyn supporters may be hesitant to back the new nominee.
