Kemper County's electorate is majority Black, a demographic reality that has kept it reliably Democratic in presidential races even as surrounding rural Mississippi counties trend sharply the other way. Its sparse population of roughly 10,000 amplifies the weight of turnout swings.
The Democratic margin in Kemper County peaked at ninety-nine points in 1936. By 1992 the county had flipped, voting Republican for the first time in many years. The 2024 margin was seventeen points, the most Democratic-leaning result in the county's modern history.
The economic context is the key. Kemper County's median household income of $46,431 sits well below state and national norms, and 25% 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 Franklin city and Liberty County.
