This rural southeast Georgia county of roughly 15,000 delivered an R+82.5 margin in 2024, placing it among the most one-sided presidential results in the state and reflecting the deep partisan sorting common across Georgia's wiregrass region.
The unraveling was not abrupt. The Democratic margin in Brantley County peaked at ninety-four points in 1932; it narrowed steadily over the late twentieth century. The 1996 election delivered the county to the Republican party for the first time in many years, by a margin of seven points. By 2024, the margin had widened further.
The economic and demographic context is severe. Brantley County's median household income of $58,239 is among the lowest of any county in the United States; 17% of residents live below the federal poverty line. The county's voting pattern over the last decade is most similar to that of Lamar County and Freestone County.
