Huerfano County's economy once centered on coal mining along the Culebra Range, and its largely Hispanic rural population has trended Republican in recent cycles, reflecting a broader realignment in small-town southern Colorado.
The Democratic margin in Huerfano County has rarely exceeded fifty-one points in modern history; the Republican margin has rarely exceeded fifty-nine points. 2024 delivered the county to the Republican candidate by nine points.
Huerfano County's demographics resemble the country more than they resemble most counties. A 78% non-Hispanic-white share, a 17% poverty rate, and a median household income of $52,526 — all within the broad national range. The county's voting pattern over the last decade is most similar to that of Tillamook County and Las Animas County.
