Kingman County sits in south-central Kansas's hard-winter-wheat corridor, where a thinly spread agricultural population has delivered some of the state's widest presidential margins for decades.
The Democratic margin in Kingman County peaked at thirty-five points in 1912. By 1980 the county had flipped, voting Republican for the first time in many years. The 2024 margin was sixty points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Kingman County's median household income of $59,842 sits well below state and national norms, and 10% 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 Decatur County and Wabaunsee County.
