A Texas Southern University survey of 1,500 likely voters conducted Aug. 6–12 finds Beto O’Rourke holding a double-digit advantage in the 2026 Democratic U.S. Senate primary. In a head-to-head test, the former El Paso congressman leads U.S. Rep. Colin Allred 58% to 38%. A separate question pairing Allred against state Rep. James Talarico shows Allred ahead 50% to 43%. On the Republican side, Attorney General Ken Paxton tops the field with 35% support in a three-way contest that includes incumbent Sen. John Cornyn at 30% and U.S. Rep. Wesley Hunt at 22%, with 13% undecided. In a two-candidate matchup, Paxton widens his edge over Cornyn to 44% versus 39%, while 17% remain undecided. The results signal competitive primaries for both parties as Texas prepares for a potentially high-profile Senate race in 2026.
