Lamar County, tucked between Atlanta's outer suburbs and Georgia's rural Black Belt fringe, turns in some of the state's most lopsided presidential results despite a population barely topping 15,000.
The unraveling was not abrupt. The Democratic margin in Lamar County peaked at ninety 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 fourteen points. By 2024, the margin had widened further.
The economic and demographic context is severe. Lamar County's median household income of $67,062 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 Heard County and Dixie County.
