Banks County, a rural Piedmont county northeast of Atlanta, recorded an R+78.2 margin in 2024 — among the widest gaps in a state where statewide races have been decided by under two points.
The unraveling was not abrupt. The Democratic margin in Banks County peaked at ninety points in 1932; 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 nineteen points. By 2024, the margin had widened further.
The economic and demographic context is severe. Banks County's median household income of $77,063 is among the lowest of any county in the United States; 11% of residents live below the federal poverty line. The county's voting pattern over the last decade is most similar to that of Grayson County and Pike County.
