Election Poll Switzerland: Results from OpinionPlus on October 17, 2023

Switzerland's bicameral Federal Assembly features the 200-seat National Council and the 46-seat Council of States. The National Council employs proportional representation across cantons, while the Council of States largely uses a majority vote system. A distinctive element is 'panachage' and 'cumulation,' allowing voters to mix candidates from various party lists or cast multiple votes for specific individuals. This empowers citizens with substantial influence over the legislature's composition, moving beyond strict party affiliations.

Switzerland's federal elections notably lack an explicit percentage-based electoral threshold, unlike Germany's 5% hurdle. Instead, the de facto barrier for National Council entry emerges from the number of seats allocated per canton. This dynamic means smaller cantons with fewer mandates demand a substantially higher vote share for a seat, while larger cantons like Zurich can see parties secure representation with a smaller percentage.

Swiss government formation defies the conventional coalition-opposition paradigm. The Federal Council, Switzerland's seven-member executive, is elected by the United Federal Assembly. For decades, its composition has adhered to the 'magic formula,' proportionally incorporating the nation's most powerful parties. This concordance system prioritizes achieving political solutions through broad consensus over transient majority coalitions.
