With fewer than 800 residents spread across the San Juan Mountains, Hinsdale routinely delivers some of the state's most lopsided margins simply because its electorate is so small that a few dozen votes can swing the percentage sharply.
The Republican margin in Hinsdale County reached its widest at fifty-eight points in 1972. The margin in 2024 was twelve points, in line with the county's deep historical pattern.
Hinsdale County's loyalty is rooted in its place. Median household income of $75,972, a 87% non-Hispanic-white share, and a population of 1,005 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 Hamilton County and Madison County.
