Incumbent Democrat Henry Cuellar's pardon by President Trump in December 2025 and his March 3 primary victory with 58% of the vote have solidified trader consensus favoring Democrats at 68% in the TX-28 House race, reflecting his resilience in the South Texas border district despite past bribery charges. Republican nominee Tano Tijerina, Webb County Judge who dominated his primary at 74%, faces an uphill battle in a Cook Political Report-rated Lean Democratic seat, where Cuellar won 53% in 2024 amid Hispanic voter loyalty and a slight Democratic partisan lean. Recent first-quarter fundraising reports show Cuellar holding a cash-on-hand edge ($764,000 vs. Tijerina's $577,000 as of mid-April), underscoring limited GOP momentum ahead of the November 3 general election.
