Henry Cuellar’s strong position in the TX-28 race stems primarily from his long incumbency, substantial fundraising edge, and the December 2025 presidential pardon that ended federal bribery charges against him. Although mid-decade redistricting made the South Texas district more Republican-leaning, with Donald Trump carrying the new lines by roughly ten points, nonpartisan ratings still classify it as Lean or Tilt Democratic. Tano Tijerina, the Republican nominee and former Democratic Webb County judge who switched parties after 2024, secured a decisive primary win and carries Trump’s endorsement, yet trails in recent polling and lacks Cuellar’s established crossover support among border voters. Traders appear to weigh these structural and legal factors more heavily than the district’s partisan shift or Tijerina’s recent convention appearances when assigning probabilities ahead of the November 3, 2026 general election.
