Medina County's sparse ranchland and small towns along the San Antonio exurban fringe have delivered lopsided Republican margins for decades, with the 2024 presidential result continuing a pattern of roughly 70-plus percent GOP support.
The Republican margin in Medina County reached its widest at forty-five points in 1972. The margin in 2024 was forty-three points, in line with the county's deep historical pattern.
Medina County's loyalty is rooted in its place. Median household income of $78,074, a 58% non-Hispanic-white share, and a population of 53,547 together describe a community whose political habits are deeply settled. The county's voting pattern over the last decade is most similar to that of Lampasas County and Real County.
