This high-plains ranching county of roughly 6,000 residents delivered a 64-point Republican margin in 2024, making it a consistent outlier even within Colorado's rural eastern corridor.
The Democratic margin in Lincoln County peaked at twenty-six points in 1896. By 1968 the county had flipped, voting Republican for the first time in many years. The 2024 margin was sixty-four points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Lincoln County's median household income of $62,861 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 Phillips County and Cheyenne County.
