Wisconsin Political History & Voting Patterns
Reliably D 1988-2012; flipped 2016; leaning D since 2020. A complete guide to how Wisconsin has voted in presidential elections, which coalitions have driven results, and how the state has shifted over time.
Historical Overview
Wisconsin may be the most evenly divided state in modern American history. Decided by less than 1 point in 2016, 2020, and 2024, it has produced some of the most dramatic political moments of the era. The Walker era (2011-2019) and the Act 10 union-stripping legislation triggered massive labor protests and recall elections. Tammy Baldwin’s Senate wins (2012, 2018, 2024) show Democrats can win statewide with a strong candidate. But Republicans consistently win state legislative seats due to aggressive gerrymandering — Wisconsin courts partially redrawn the map in 2024. The Madison-Milwaukee axis provides Democratic margins; the Fox Valley, Waukesha County, and rural Wisconsin provide Republican counter-pressure.
