Mohave County, anchored by Kingman along the I-40 corridor, posts some of the widest presidential margins in Arizona — its sparse, rural expanse and retiree-heavy demographics have produced Republican advantages exceeding 50 points in recent cycles.
The Democratic margin in Mohave County peaked at forty-nine points in 1932. By 1968 the county had flipped, voting Republican for the first time in many years. The 2024 margin was fifty-six points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Mohave County's median household income of $57,684 sits well below state and national norms, and 16% 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 Cumberland County and Rhea County.
