Incumbent Democrat Henry Cuellar holds a strong position in Texas’s 28th congressional district ahead of the November 2026 general election. Cuellar secured renomination with 58% in the March Democratic primary and benefits from a December 2025 presidential pardon that resolved prior federal charges, removing a key vulnerability. Nonpartisan ratings classify the seat as Lean or Tilt Democratic, reflecting his personal support among Hispanic voters in South Texas despite the redrawn map’s modest Republican tilt (Cook PVI R+2/R+3) and Donald Trump’s 2024 margin there. Republican nominee Tano Tijerina won his primary comfortably but trails in fundraising and faces an uphill effort to overcome Cuellar’s incumbency and established local networks in a district where down-ballot Democratic performance has historically exceeded the presidential baseline.
