Morrison's heavily rural, timber-country landscape anchors a presidential margin that has widened each cycle since 2008, reaching R+55.9 in 2024 and placing it among the most one-sided counties in a competitive battleground state.
The Democratic margin in Morrison County peaked at forty-nine points in 1932. By 2000 the county had flipped, voting Republican for the first time in many years. The 2024 margin was fifty-six points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Morrison County's median household income of $69,446 sits well below state and national norms, and 11% of residents live below the federal poverty line. The shift here is part of a broader realignment of working-class places across the country. The county's voting pattern over the last decade is most similar to that of Worth County and Van Buren County.
