Koalitionen - Wahl-O-Mat Bundestagswahl 2021 is a Chrome add-on developed by Marcel Carlé. It enhances the functionality of the Wahl-O-Mat for the German federal election in 2021 by introducing possible coalitions.

The add-on calculates the positions of the coalitions based on the answers provided by the parties and their share in the respective coalition. Users can select not only individual parties but also some potential coalitions during the party selection process. This allows users to see how a coalition might align with various statements.

Furthermore, users can examine how the statements of the participating parties align with the calculated coalition position for each coalition.

For additional information, users can access the source code on GitHub and view the survey data used for calculations on the DAWUM website. The Wahl-O-Mat itself can be accessed through the provided link.

Please note that the review should not include personal judgments or contact information.
