Henry Cuellar's position as the long-serving Democratic incumbent in Texas's 28th district underpins the 92% trader consensus for his victory, reinforced by consistent polling leads of 11–20 points in recent surveys and a fundraising advantage exceeding $1 million over Republican challenger Tano Tijerina. Redistricting completed in 2025 preserved the district's Democratic lean, while Cuellar's clearance from prior legal matters via presidential pardon in late 2025 removed a key vulnerability. Tijerina, a former county judge who switched parties, secured endorsements from prominent Republicans but trails in cash reserves and faces a compressed timeline with Election Day three days away. Late shifts in turnout among border-region voters or unforeseen developments could narrow the margin, though models project Cuellar winning roughly 99% of simulated outcomes based on current fundamentals and polling.
