Benton County anchors the booming Bentonville metro, home to Walmart's global headquarters, drawing a wave of corporate transplants that has made it one of Arkansas's most populous and economically dynamic counties while sustaining deep-red margins.
The shift began with civil rights. 1952 marked the realignment in Benton County, by a thirty-eight points margin. The Republican margin reached its widest at fifty-six points in 1972. The 2024 margin was twenty-seven points.
The political shift has tracked, in Benton County, the political shift of the South more broadly. A 60% non-Hispanic-white share, a median household income of $93,506, and a 8% poverty rate describe the demographic context. The county's voting pattern over the last decade is most similar to that of Knox County and Woodford County.
