Home to a substantial Ute Mountain Ute population and a longstanding ranching economy, Montezuma County has voted Republican by double digits in recent presidential cycles while local water rights and tribal sovereignty debates cut across party lines.
The Democratic margin in Montezuma County peaked at ninety-two points in 1896. By 1968 the county had flipped, voting Republican for the first time in many years. The 2024 margin was twenty-one points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Montezuma County's median household income of $65,244 sits well below state and national norms, and 13% 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 Custer County and Beaverhead County.
