Tano Tijerina is running against Henry Cuellar (D, incumbent).
TX-28 is a top GOP pickup target in 2026. Trump won the redrawn district 53%-46% in 2024, a 15-point swing from Biden's 2020 win. Cuellar, who was pardoned by Trump after facing federal bribery charges, won his 2024 race by just 6 points - his narrowest margin ever. Tijerina's switch from Democrat to Republican and his endorsement by Trump make him the GOP's strongest recruit to flip this historically Democratic South Texas seat.
Cook Political Report rates TX-28 as Lean Democratic. Trump endorsed Tijerina in January 2026, calling his views "stronger, better, and far less tainted than Henry's." Cuellar ran 25 points ahead of Allred in Webb County, showing strong personal brand among Latino voters. Tijerina faces Eileen Day in the March 3 GOP primary. New district map eliminates half of Cuellar's current constituents.
Key dates to watch: Primary on March 3, 2026 and General Election on November 3, 2026.
