Routt County, anchored by Steamboat Springs, combines a small permanent population with a high-income, resort-driven economy — a mix that has pushed its presidential margins sharply leftward even as surrounding mountain counties trend more competitive.
The Democratic margin in Routt County reached its widest at eighty points in 1896. The margin in 2024 was twenty-eight points — still decisive.
Routt County's loyalty is rooted in its place. Median household income of $106,489, a 81% non-Hispanic-white share, and a population of 25,084 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 Gunnison County and Blaine County.
