Partisan Politics in the 21st Century South: The Fading Impact of Antebellum Slavery

Abstract

Acharya, Blackwell, and Sen (2018) argue that antebellum slavery is directly related to racial conservatism and support for the Republican Party in the modern South. Yet during the last two decades, the South has begun a subtle but still very significant partisan shift to the left. Areas where population growth has stagnated (or actually declined) have tended to become more Republican; Democratic support has been bolstered by higher population growth. Significantly, local population growth and historic slave populations are largely unrelated. I examine the extent to which antebellum slavery influences county-level southern White partisanship and racial resentment during the second decade of the 21st century. Over the course of this time period, the impact of antebellum slavery evaporates. Not coincidentally, county-level population growth is strongly associated with increased Democratic identification and more progressive racial attitudes at or near the end of this time frame.
