The southern section includes Kingman, the county seat, and other cities, as well as part of theMojave Desert.

Since 2008, Mohave has taken over fromGraham andYavapai as the “reddest” county in the state, and in 2024, it stood as such by twenty-one percentage points. No Democratic presidential nominee has carried Mohave County sinceLyndon Johnson, who, despite thehome state advantage of Arizona nativeBarry Goldwater, did so in 1964, by a margin of only 152 votes. In the 1990s,Bill Clinton came very close to winning this county, if not because of a combination of significant nationwide rural appeal and third-party candidateRoss Perot's Western appeal himself.
