Apache County's electorate is shaped by the Navajo and Hopi nations, which together cover most of its land area and account for the Democratic-leaning margins that have defined its presidential results for decades.
The Democratic margin in Apache County peaked at forty-five points in 1936. By 1984 the county had flipped, voting Republican for the first time in many years. The 2024 margin was nineteen points, the most Democratic-leaning result in the county's modern history.
The economic context is the key. Apache County's median household income of $41,438 sits well below state and national norms, and 31% 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 Hale County and Hancock County.
