Incumbent Rep. Henry Cuellar's victory in the March 3 Democratic primary with 58% secures his party's 65.5% trader consensus lead in the TX-28 House race, reflecting his entrenched support in the heavily Hispanic border district despite redistricting to an R+2 Cook PVI where Trump won 60.6% in 2024. Republican nominee Webb County Judge Tano Tijerina's dominant 74% primary win sets up a competitive general on November 3, but Cuellar's fundraising edge ($1.6M raised vs. Tijerina's $937K as of mid-April) and Trump's December 2025 pardon resolving federal charges bolster Lean Democratic ratings from Cook and Sabato. No major developments in the past 30 days; competitive cash positions signal potential volatility ahead of early voting.
