Kittson sits on Minnesota's northwestern edge along the Canadian border, where wheat and sugar-beet agriculture dominates the landscape and has anchored Republican margins exceeding 20 points in every presidential race since 2008.
The county's recent history is a story of close margins. The Democratic margin reached forty-eight points in 1936; the Republican margin reached sixty-nine points in 1904. Most other elections have been decided by single-digit points.
Kittson County's demographics — a population of 4,084, a 93% non-Hispanic-white share, a median household income of $76,100 — situate the county close to national averages on several dimensions. The county's voting pattern over the last decade is most similar to that of Steele County and Price County.
