The Electoral System in Baden-Württemberg

Since the 2022 electoral reform, Baden-Württemberg employs a personalized proportional representation system featuring two votes. Gone are the days of the single-vote model: voters now cast separate ballots for their constituency representative (first vote) and the strength of the state list (second vote). This new system aims to boost women's representation and diversity within the Landtag through closed state lists, while maintaining a minimum of 120 seats overall.

Electoral Thresholds

In Baden-Württemberg, the classic five-percent threshold dictates entry into the Landtag. Given the state's political landscape, dominated by strong Green and conservative poles, this hurdle often proves an existential challenge for smaller parties like the FDP or The Left. Unlike at the federal level, no basic mandate clause exists here; entry is strictly tied to the share of second votes.

Government Formation and Traditions

Baden-Württemberg pioneered Germany's first Green-conservative coalition, led by the Greens. This constellation long served as a pragmatic model for the future. Ahead of the 2026 election, where Minister-President Kretschmann will not seek re-election, new alliances like conservative-social democrat or even three-party coalitions involving the FDP are emerging as focal points to forge stable majorities beyond the strengthening fringes.
