2023 Zürich cantonal elections

The Executive Council contains 7 members elected using a two-round majoritarian system. In the first round, electors have up to seven votes and the 7 most-voted candidates reaching an overall majority (>50%) are elected. If seats remain to be filled, a runoff is held where electors have as many votes as seats remaining, and the candidates with the most votes (simple plurality) are elected.[3][4]

The Cantonal Council is elected using open-list proportional representation, with canton-wide apportionment of seats and allocation into 18 constituencies (biproportional apportionment). In each constituency, voters have as many votes as there are seats to fill (panachage is permitted); these votes each count both for the candidate and for the list they stand in. These votes counts are divided by the seats count to give fictional electors counts which can be summed up fairly throughout the canton.

Using the fictional electors counts, each party above the threshold (reaching 5% in at least one constituency) is apportioned seats canton-wide, which are then shared among their constituency lists. In each constituency list, the seats are attributed to the candidates reaching the most votes.[3][4]

Cantonal elections in Zürich are typically held in April or late March, but the presence of both a federal referendum date on 12 March and holidays meant the cantonal elections had to be pusher earlier, to mid-February.[5] Had a second round been needed, it would have been held on 16 April.[5]

All seven incumbents ran for re-election: Mario Fehr (ind.), Jacqueline Fehr (SP), Ernst Stocker (SVP), Sylvia Steiner (CVP), Carmen Walker Späh (FDP), Martin Neukom (Grüne), and Natalie Rickli (SVP). Mario Fehr was elected in 2011 then re-elected in 2015 and 2019 as a social democrat, but left the party in 2021 and contested this election as an independent.[5]

The FDP fielded Peter Grünenfelder as their second candidate in hope of retaking their seat lost in 2015; the SP fielded Priska Seiler Graf as their second candidate to compensate for Mario Fehr's defection. Benno Scherrer runs for the Green-Liberals, hoping to take a seat as the fourth-largest party in the cantonal council.

Minor candidates were Anne-Claude Hensch for the Alternative List, Daniel Sommer for the EVP; Patrick Jetzer for Aufrecht and Josua Dietrich for the Free List both ran as opponents to Covid restrictions. Former SVP member Hans-Peter Amrein also ran as an independent, as did Bernhard Schmidt and Peter Vetsch.[5]

Candidacies could be submitted until 28 November 2022, 17 candidates ran in total.

The table below lists contesting parties represented in the Cantonal Council before the election.[5]

Lists could be submitted until 5 December 2022. 13 parties contested this election, as many as in 2019, with 1687 candidates in total in the canton.

The SVP, SP, FDP, GLP, Greens, and Mitte all ran full slates of 180 candidates, while the EVP (177 candidates), AL (139), EDU (132), and Aufrecht/Free List (132) also ran in all 18 constituencies. The Party of Labour (23 candidates) only contests in the constituencies of the city of Zürich, and the lists Yes to stop growth and SansPapierPolitiques both consist of a single candidate.

Note: percentages here are calculated based on the amount of valid votes (excluding blank and invalid votes) so that the absolute majority is at exactly 50%, but may result in candidates reaching over 100% of the valid votes.

All seven incumbents were re-elected without the need for a second round.[15] Mario Fehr topped the polls with 74%, nine points below his 2019 results but nonetheless an increase of twenty thousand votes. He was followed by the two SVP candidates Natalie Rickli and Ernst Stocker, both seeing large increases in votes compared to 2019. Green councillor Martin Neukom finished 4th after being the surprise of 2019, ahead of SP councillor Jacqueline Fehr, while Sylvia Steiner and Carmen Walker Späh both defended their seats with over 56%, a margin of twenty-five thousand votes over Priska Seiler Graf who failed to swing the majority in the executive to the left.[16]

This election saw little movement for most parties. The most significant changes were the Green Party losing three seats, while The Centre (merger of the CVP and BDP) re-gained three, mainly owing to the inclusion of former BDP votes that failed to pass the threshold in 2019. The SVP retained the first place and gained one seat, as did the Social-Democrats and the Green-Liberals; the EVP, AL, and EDU all lost one seat each, and the FDP's number of seats remained consistent. No new party passed the threshold, Aufrecht and the Free List came closest but did not win any seats.

The "Climate Alliance" (SP, GLP, Greens, EVP, AL) lost three seats overall but maintained a narrow majority of a single seat, while the bourgeois parties (SVP, FDP, CVP) gained four seats but failed to re-gain the majority. This puts once again the Green-Liberals as kingmakers for various legislative majorities in the elected Cantonal Council, left-leaning for social and climate issues but right-leaning for economic issues.[16]
