Grant County's economy has long orbited the copper industry around Silver City, producing a blue-collar demographic mix that keeps presidential margins closer than in most of the state's rural south — the 2024 result landed at D+5.1.
The Democratic margin in Grant County reached its widest at forty-four points in 1964. The margin in 2024 was five points — still decisive.
Grant County's loyalty is rooted in its place. Median household income of $44,958, a 62% non-Hispanic-white share, and a population of 27,775 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 St. Clair County and Calhoun County.
