Randolph County, anchored by Asheboro in the Piedmont Triad's southern fringe, delivers some of the state's most lopsided presidential margins—its rural manufacturing heritage and sparse urban core produce an electorate that has moved steadily away from statewide competitive norms.
The unraveling was not abrupt. The Democratic margin in Randolph County peaked at forty-seven points in 1912; it narrowed steadily over the late twentieth century. The 2004 election delivered the county to the Republican party for the first time in many years, by a margin of forty-nine points. By 2024, the margin had widened further.
The economic and demographic context is severe. Randolph County's median household income of $61,022 is among the lowest of any county in the United States; 15% of residents live below the federal poverty line. The county's voting pattern over the last decade is most similar to that of Davidson County and Avery County.
