Cisneros won Bexar county (San Antonio voters) 73.4% to 20.7%. They saved her.
The 2 Rio Grande Valley counties went big for Cuellar. He won Starr with 69.9% to 27.5%, and Webb 59.5% to 37.5%, which solidly demonstrates the conservativism of the valley.
Eddie Lucio won the other part of the valley, against a major progressive challenge in 2020. Hildago is his stomping ground.
