Montrose County anchors Colorado's Western Slope, where an economy built on agriculture, energy extraction, and outdoor recreation has produced some of the state's most consistent Republican margins over the past two decades.
The Democratic margin in Montrose County peaked at seventy-five points in 1896. By 1968 the county had flipped, voting Republican for the first time in many years. The 2024 margin was thirty-three points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Montrose County's median household income of $72,120 sits well below state and national norms, and 12% 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 Delta County and Klamath County.
