A sparsely populated plains county in eastern Colorado, Kit Carson recorded an R+68.3 margin in 2024 — among the widest gaps in the state — reflecting the heavily rural, agricultural character of the region.
The Democratic margin in Kit Carson County peaked at nineteen points in 1916. By 1968 the county had flipped, voting Republican for the first time in many years. The 2024 margin was sixty-eight points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Kit Carson County's median household income of $70,259 sits well below state and national norms, and 10% 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 Morrill County and Polk County.
