Anchoring the state's Lake Superior shoreline and northwoods counties, this district delivered a 25-point Republican margin in 2024 — among the widest in Wisconsin — reflecting a rural, largely white electorate with longstanding conservative voting patterns.
Across the recorded series it reached a Democratic high of 46.0 points in 1932 and a Republican high of 65.4 points in 1920. The 2024 margin was 20.3 points.
A population of 178,031, a 91% non-Hispanic-white share, and a median household income of $86,129 describe the district. The district's voting pattern over the last decade is most similar to that of State Senate District 19 and State Senate District 2.
