The German Electoral System
Germany's mixed-member proportional representation combines local constituency races with party-list voting. State (Bundesland) elections use similar rules to federal elections: a 5% threshold, D'Hondt allocation, and coalition governments. Baden-Württemberg and Bavaria held elections on March 9, 2026, testing Chancellor Friedrich Merz's CDU/CSU coalition strategy.
MMP Explained
Voters cast two votes: the first for a local candidate (direct mandate), the second for a party list. The second vote determines the overall party composition. Seats are allocated proportionally among parties above 5%, ensuring that the final parliament reflects the party vote share while preserving local representation.
Key Takeaways from March 2026
CDU won 34% in Baden-Württemberg; the Greens lost 8 points from 2021. AfD remained at 14%, below the national average. The 5% threshold eliminated smaller parties. These results signal a shift toward the center-right and test Merz's ability to form stable coalitions at the federal level.
6 Facts About German State Elections
- 16 states (Länder) each have their own parliament and election cycles.
- The 5% threshold applies in all states except Bavaria (where it is 5% or one direct mandate).
- D'Hondt slightly favors larger parties compared to Sainte-Laguë.
- Coalition negotiations typically take weeks after election day.
- AfD has never been part of a governing coalition at state or federal level.
- Baden-Württemberg and Bavaria are economically powerful states with outsized influence.
How the D'Hondt Method Works
For each seat to be allocated, compute the quotient votes ÷ (seats already won + 1) for each party. Award the seat to the party with the highest quotient. Repeat until all seats are allocated. This method slightly favors larger parties and is used in most German states.
Expert Tips on Coalition Building
When modeling coalitions: (1) CDU typically prefers Black-Green or Black-Yellow over Grand Coalition; (2) Traffic Light (SPD+Grüne+FDP) requires all three above 5%; (3) BSW (Sahra Wagenknecht) complicates traditional left alliances; (4) AfD remains a pariah for mainstream parties.

Frequently Asked Questions
What is Germany's mixed-member proportional representation (MMP)?
Germany uses MMP: voters cast two votes — one for a local candidate (first vote) and one for a party list (second vote). The second vote determines the overall party composition. Seats are allocated proportionally among parties that clear the 5% threshold, using the D'Hondt method in most states.
What is the 5% threshold in German state elections?
Parties must win at least 5% of the vote (or three direct mandates) to enter the state parliament. Votes for parties below the threshold are effectively discarded for seat allocation. This prevents extreme fragmentation but can exclude smaller parties.
How does the D'Hondt method work?
D'Hondt allocates seats by repeatedly awarding the next seat to the party with the highest quotient (votes ÷ (seats already won + 1)). It slightly favors larger parties compared to pure proportional methods like Sainte-Laguë.
What coalitions are common in German state politics?
Common coalitions include: CDU+SPD (Grand Coalition), CDU+Grüne (Black-Green), CDU+FDP (Black-Yellow), SPD+Grüne+FDP (Traffic Light), and SPD+Grüne+BSW. Bavaria often sees CSU+Freie Wähler.
Why did the Greens lose ground in the March 2026 elections?
The Greens lost 8 points from 2021 in Baden-Württemberg, partly due to energy policy backlash, coalition fatigue, and voter shifts to CDU and AfD. Chancellor Merz's CDU/CSU performed strongly, testing his federal coalition strategy.
How many seats does each German state parliament have?
Seat counts vary: Baden-Württemberg 154, Bavaria 205, NRW 195, Hesse 137, Lower Saxony 137, Saxony 119, Thuringia 90, Brandenburg 88. These reflect population and constitutional rules.
