Ken Paxton Defeats Sen. John Cornyn in Texas GOP Primary Runoff
Texas Attorney General Ken Paxton crushed four-term incumbent Sen. John Cornyn 64%-36% in the May 26, 2026 Republican primary runoff — the widest primary defeat of a sitting U.S. senator in nearly five decades. Trump had endorsed Paxton one week before the vote, overriding his own Senate leadership's backing of Cornyn. Senate Majority Leader Thune immediately called on Republicans to "pivot" to supporting Paxton, while Democrat James Talarico, who will face Paxton in November, declared him "the most corrupt politician in America."
