Tucked into Georgia's northwest tip and functionally tied to Chattanooga, Tennessee, Catoosa County has delivered Republican presidential margins above 50 points in recent cycles, reflecting the deep-red pattern common across Appalachian Georgia.
The unraveling was not abrupt. The Democratic margin in Catoosa County peaked at seventy-seven points in 1932; it narrowed steadily over the late twentieth century. The 1980 election delivered the county to the Republican party for the first time in many years, by a margin of nine points. By 2024, the margin had widened further.
The economic and demographic context is severe. Catoosa County's median household income of $74,639 is among the lowest of any county in the United States; 10% of residents live below the federal poverty line. The county's voting pattern over the last decade is most similar to that of Bradley County and Pearl River County.
