In short: The 2025 German federal election, held on 23 February, was defined by a volatile landscape where nearly half of the major parties risked falling below the critical 5% threshold. This electoral hurdle, combined with complex rules regarding constituency wins, created significant uncertainty about which parties would ultimately secure seats in the Bundestag.

The German electoral system requires parties to clear a 5% threshold of federally valid second votes to enter the Bundestag. Alternatively, parties can secure representation by winning at least three constituencies. This secondary rule became a focal point of legal debate after it was abolished in 2022, only to be reinstated by the Federal Constitutional Court. The provision is vital for parties like Die Linke, which gained full proportional representation in 2021 despite receiving only 4.9% of the national vote, and the Christian Social Union (CSU), which operates exclusively in Bavaria.

Heading into the 2025 snap election, the political environment was particularly tense. While the Social Democratic Party (SPD), the Christian Democratic Union (CDU), the Alternative for Germany (AfD), and Alliance 90/The Greens were comfortably above the 5% mark, other significant players faced a precarious situation. The Free Democratic Party (FDP)—a member of the collapsed Traffic Light Coalition—along with Die Linke and the newly formed Sahra Wagenknecht Alliance (BSW), all hovered near the threshold. This proximity to the 5% limit meant that even small shifts in voter sentiment could drastically alter the composition of the parliament.

To navigate this uncertainty, voters and analysts relied on a variety of polling organizations. Aggregators like Europe Elects maintain strict standards for inclusion, favoring firms that belong to professional associations and demonstrate methodological rigor. Organizations such as Allensbach, Forsa, and Infratest dimap are frequently cited for their transparency. Conversely, aggregators often exclude firms like Civey, Wahlkreisprognose, and the Democracy Institute due to concerns regarding their methodology or lack of professional affiliation. Understanding these distinctions is essential for interpreting the polling data that shaped the public discourse leading up to the February vote.
