Bolivar County sits in the heart of the Mississippi Delta, where a majority African American population and persistent rural poverty have produced some of the most reliably Democratic presidential margins in the state for decades.
The Democratic margin in Bolivar County peaked at ninety-two points in 1936. By 1976 the county had flipped, voting Republican for the first time in many years. The 2024 margin was twenty-four points, the most Democratic-leaning result in the county's modern history.
The economic context is the key. Bolivar County's median household income of $39,585 sits well below state and national norms, and 33% 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 Lee County and Bamberg County.
