Cheyenne County sits on Colorado's eastern plains with a population under 2,500, and its agricultural economy and sparse settlement have produced some of the state's most consistent and wide Republican presidential margins for decades.
The Democratic margin in Cheyenne County peaked at twenty points in 1912. By 1980 the county had flipped, voting Republican for the first time in many years. The 2024 margin was seventy-eight points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Cheyenne County's median household income of $70,865 sits well below state and national norms, and 8% of residents live below the federal poverty line. The shift here is part of a broader realignment of working-class places across the country. The county's voting pattern over the last decade is most similar to that of Dallam County and Washington County.
