Incumbent Democratic Representative Henry Cuellar secured his party's nomination in the March 2026 primary, positioning him against Republican nominee Tano Tijerina in the November general election for Texas's 28th congressional district. The district's South Texas demographics, including substantial Hispanic voter blocs and border communities, have historically supported Cuellar's reelection bids, contributing to the trader consensus reflected in current pricing that favors the Democratic outcome. With both major-party candidates now set following the primaries, limited new developments have emerged in recent weeks to shift assessments of the race, though factors such as turnout patterns, national political environment, and candidate fundraising could still influence the final margin.
