Anchored by Roswell in the Pecos Valley, Chaves County has trended heavily toward Republican candidates in recent cycles, posting a 44.8-point margin in 2024 despite sitting within a state that leans Democratic statewide.
The Democratic margin in Chaves County peaked at forty-two points in 1916. By 1968 the county had flipped, voting Republican for the first time in many years. The 2024 margin was forty-five points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Chaves County's median household income of $52,938 sits well below state and national norms, and 24% 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 Wells County and Adams County.
