Anoka County sits on Minneapolis's northern fringe and has shifted from a competitive swing county to a reliably Republican-leaning one over the past four election cycles, tracking a broader exurban realignment seen across the Midwest.
The Democratic margin in Anoka County has rarely exceeded forty-one points in modern history; the Republican margin has rarely exceeded sixty-seven points. 2024 delivered the county to the Republican candidate by four points.
Anoka County's demographics resemble the country more than they resemble most counties. A 75% non-Hispanic-white share, a 7% poverty rate, and a median household income of $101,869 — all within the broad national range. The county's voting pattern over the last decade is most similar to that of West Baton Rouge Parish and Tyrrell County.
