Incumbent Sen. John Cornyn faces Texas Attorney General Ken Paxton in the Republican primary runoff on May 26, with early voting starting May 18, determining the GOP nominee against Democratic state Rep. James Talarico, who won his primary in March. Recent polls, including a University of Houston survey showing Paxton up 48-45 and conflicting partisan soundings, underscore the intra-party divide fueling trader caution, as Paxton trails generic Democrats while Cornyn leads 51-49 per Deep Root Analytics. Texas' Republican lean and suburban shifts keep the race tight at 54.5% GOP odds, with runoff outcome, turnout among primary voters, and national midterm headwinds as key separators.
