Graham County's high desert terrain and small-town economy have produced presidential margins above R+40 in each of the past several cycles, making it a consistent outlier even within a state that has trended competitive at the statewide level.
The Democratic margin in Graham County peaked at sixty-five points in 1936. By 1968 the county had flipped, voting Republican for the first time in many years. The 2024 margin was forty-eight points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Graham County's median household income of $67,325 sits well below state and national norms, and 17% 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 Winkler County and Sutton County.
