Wisconsin Assembly District 21 sits close enough to the competitive middle that a 4.6-point Republican presidential lean offers no guarantee of comfort down-ballot, making it a consistent target for both parties in state legislative contests.
The Democratic margin in Wisconsin 21st State House 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.
