Cook County sits in the wiregrass region of south Georgia, where a predominantly rural, agricultural economy aligns with some of the state's most lopsided presidential margins — the 2024 gap exceeded 46 points.
The unraveling was not abrupt. The Democratic margin in Cook County peaked at ninety-six points in 1932; it narrowed steadily over the late twentieth century. The 2000 election delivered the county to the Republican party for the first time in many years, by a margin of sixteen points. By 2024, the margin had widened further.
The economic and demographic context is severe. Cook County's median household income of $53,651 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 Irwin County and Simpson County.
