Norman County stretches across the flat eastern edge of the Red River Valley, where a dwindling, aging rural population and farm-dependent economy have tracked a steady rightward shift in presidential voting over the past decade and a half.
The Democratic margin in Norman County has rarely exceeded forty-four points in modern history; the Republican margin has rarely exceeded seventy-one points. 2024 delivered the county to the Republican candidate by twenty-two points.
Norman County's demographics resemble the country more than they resemble most counties. A 89% non-Hispanic-white share, a 10% poverty rate, and a median household income of $72,260 — all within the broad national range. The county's voting pattern over the last decade is most similar to that of Kittson County and Benson County.
