In the Texas Republican U.S. Senate primary runoff set for May 26, trader consensus favors Attorney General Ken Paxton at 65.5% implied probability over incumbent Senator John Cornyn's 32.5%, reflecting Paxton's post-primary polling surge—including a March 20 Impact Research survey showing him ahead 53%-37%—despite Cornyn's massive spending advantage in the March 3 first round, where neither secured a majority. Paxton's strong appeal to the GOP base, bolstered by his high-profile legal battles and alignment with Trump-aligned voters, contrasts with Cornyn's establishment backing and criticisms over bipartisan votes, amid President Trump's reluctance to endorse. Upcoming early voting and potential endorsements could shift dynamics in this closely watched intraparty contest.
