Randolph County, tucked into Arkansas's northeast corner along the Missouri border, recorded an R+63.7 presidential margin in 2024 — among the widest in the state — reflecting the deep rural realignment that has reshaped the Ozark fringe over the past two decades.
The unraveling was not abrupt. The Democratic margin in Randolph County peaked at eighty-one points in 1932; it narrowed steadily over the late twentieth century. The 2008 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. Randolph County's median household income of $50,911 is among the lowest of any county in the United States; 22% of residents live below the federal poverty line. The county's voting pattern over the last decade is most similar to that of Lawrence County and Fulton County.
