U.S. House
Each result reflects the U.S. House district as it was drawn for that election; redistricting has redrawn these lines over time, so they can differ from the current 120th-Congress district shown on the map above.
Home to the University of Wisconsin–Madison and a dense concentration of state-government workers, WI-02 delivered a 38-point Democratic margin in 2024 — among the widest in the Midwest — driven by high turnout in Dane County's college-educated electorate.
Across the recorded series it reached a Democratic high of 42.0 points in 2008 and a Republican high of 65.5 points in 1920. Between 2020 and 2024 the district moved 1.6 points toward the Republican candidate; the 2024 margin was 40.0 points.
A population of 736,820, a 79% non-Hispanic-white share, and a median household income of $87,636 describe the district. The district's voting pattern over the last decade is most similar to that of Congressional District 4 and Congressional District 5.
The congressional districts whose fingerprint — 2000–2024 trajectory, demographics, ancestry, religion — sits closest to this one, and why.
Twin score (0–100) = weighted cosine between tier-standardized fingerprints: presidential margins 2000–2024 with 12-yr trend and elasticity, ACS income, age, education, population and race, top reported ancestries, and religious adherence — chips name the closest-shared dimensions and the widest gap.
