Wisconsin's 4th anchors Milwaukee's urban center, where a D+51 presidential margin reflects one of the most lopsided partisan distributions in the region, driven by dense population, a large Black electorate, and concentrated labor union membership.

Across the recorded series it reached a Democratic high of 52.8 points in 2020. Between 2020 and 2024 the district moved 1.3 points toward the Republican candidate; the 2024 margin was 51.6 points.

A population of 736,400, a 45% non-Hispanic-white share, and a median household income of $60,201 describe the district. The district's voting pattern over the last decade is most similar to that of Congressional District 11 and Congressional District 7.
