Demographics
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.
The Democratic margin in Wisconsin 4th Congressional District peaked at fifty-six points in 1936. By 1960 the district had flipped, voting Republican for the first time in many years. The 2024 margin was thirty-eight points, the most Democratic-leaning result in the district's modern history.
The economic context is the key. The median household income of $64,435 sits well below state and national norms, and 17% of residents live below the federal poverty line. The shift here is part of a broader realignment of working-class places across the country.
