Charlton, a sparsely populated county bordering Florida and the Okefenokee Swamp, recorded a 56-point Republican presidential margin in 2024, placing it among the state's most one-sided jurisdictions in recent cycles.
The unraveling was not abrupt. The Democratic margin in Charlton County peaked at eighty-nine points in 1936; it narrowed steadily over the late twentieth century. The 1984 election delivered the county to the Republican party for the first time in many years, by a margin of ten points. By 2024, the margin had widened further.
The economic and demographic context is severe. Charlton County's median household income of $61,276 is among the lowest of any county in the United States; 18% of residents live below the federal poverty line. The county's voting pattern over the last decade is most similar to that of Anderson County and Larue County.
