Richmond County, which consolidates with the city of Augusta, delivers some of the widest Democratic margins in eastern Georgia, driven by a majority-Black electorate and an urban core that has trended consistently leftward across recent cycles.
The Democratic margin in Richmond County peaked at eighty-six points in 1936. By 1992 the county had flipped, voting Republican for the first time in many years. The 2024 margin was thirty-six points, the most Democratic-leaning result in the county's modern history.
The economic context is the key. Richmond County's median household income of $55,637 sits well below state and national norms, and 20% of residents live below the federal poverty line. The shift here is part of a broader realignment of working-class places across the country. The county's voting pattern over the last decade is most similar to that of Fredericksburg city and Richland County.
