Comanche County sits in the shortgrass prairie of south-central Kansas with fewer than 2,000 residents, and its 2024 presidential margin of R+68.3 reflects the lopsided partisanship typical of the state's most sparsely settled range counties.
The Democratic margin in Comanche County peaked at twenty-one points in 1936. By 1968 the county had flipped, voting Republican for the first time in many years. The 2024 margin was sixty-eight points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Comanche County's median household income of $54,545 sits well below state and national norms, and 9% 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 Carson County and Cimarron County.
