Incumbent Henry Cuellar maintains a strong lead in the TX-28 race due to his long tenure representing the South Texas district since 2005, established local networks, and demonstrated crossover support among Hispanic voters in a majority-Latino area. Recent polling shows him ahead by double digits, and forecasters rate the contest Lean or Tilt Democratic despite Republican mid-decade redistricting that aimed to improve GOP prospects. Trump’s December 2025 pardon of Cuellar on prior federal charges, followed by repeated public criticism of the congressman’s decision to remain a Democrat and fresh endorsement of challenger Tano Tijerina, has energized Republican efforts around border security and party loyalty themes. Tijerina’s local profile as Webb County judge and fundraising provide a base, yet the timing of early voting and Cuellar’s incumbency advantages continue to shape trader consensus around the November 3 outcome.
