Montgomery County's R+53 margin in 2024 places it among Georgia's most one-sided presidential results, reflecting patterns common to small, rural counties in the state's southeastern interior where population has steadily declined for decades.
The unraveling was not abrupt. The Democratic margin in Montgomery County peaked at ninety-five 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 eighteen points. By 2024, the margin had widened further.
The economic and demographic context is severe. Montgomery County's median household income of $51,941 is among the lowest of any county in the United States; 21% of residents live below the federal poverty line. The county's voting pattern over the last decade is most similar to that of Berrien County and Schley County.
