With fewer than 600 residents spread across rugged 13,000-foot terrain, San Juan County delivered a 32-point Democratic margin in 2024 — one of the widest in the state despite, or perhaps because of, its extreme isolation and tight-knit mountain-town character.
Across the recorded series it reached a Democratic high of 97.6 points in 1896 and a Republican high of 26.4 points in 1984. Between 2020 and 2024 the county moved 7.0 points toward the Democratic candidate; the 2024 margin was 31.9 points.
A population of 724, a 76% non-Hispanic-white share, and a median household income of $77,824 describe the county. The county's voting pattern over the last decade is most similar to that of Grand County and La Plata County.
