Conejos County, nestled in Colorado's San Luis Valley, has one of the state's highest shares of Hispanic residents yet recorded an R+17.8 margin in 2024 — a pattern that reflects broader rural demographic realignment playing out across the Mountain West.
The Democratic margin in Conejos County has rarely exceeded ninety-two points in modern history; the Republican margin has rarely exceeded sixty points. 2024 delivered the county to the Republican candidate by eighteen points.
Conejos County's demographics resemble the country more than they resemble most counties. A 55% non-Hispanic-white share, a 12% poverty rate, and a median household income of $50,978 — all within the broad national range. The county's voting pattern over the last decade is most similar to that of Gogebic County and Poweshiek County.
