Telfair's rural, majority-Black population coexists with some of the widest Republican presidential margins in Georgia, a pattern common across the state's economically distressed wiregrass and coastal plain counties.
The unraveling was not abrupt. The Democratic margin in Telfair County peaked at ninety-three points in 1920; it narrowed steadily over the late twentieth century. The 2004 election delivered the county to the Republican party for the first time in many years, by a margin of fifteen points. By 2024, the margin had settled into deep Republican territory.
The economic and demographic context is severe. Telfair County's median household income of $50,929 is among the lowest of any county in the United States; 24% of residents live below the federal poverty line. The county's voting pattern over the last decade is most similar to that of Taylor County and Ben Hill County.
