Sharkey County's heavily Black majority population — among the highest proportions in Mississippi — anchors a Democratic lean that has held across multiple election cycles, even as surrounding Delta counties have shifted toward Republicans.
The unraveling was not abrupt. The Democratic margin in Sharkey County peaked at 100 points in 1932; it narrowed steadily over the late twentieth century. The 1976 election delivered the county to the Republican party for the first time in many years, by a margin of eleven points. By 2024, the margin had settled into deep Republican territory.
The economic and demographic context is severe. Sharkey County's median household income of $40,000 is among the lowest of any county in the United States; 31% of residents live below the federal poverty line. The county's voting pattern over the last decade is most similar to that of Norfolk city and Dallas County.
