"Partial Rerun: Berlin's 2021 German Federal Election"
Berlin held a partial rerun of the 2021 German federal election due to mishaps in the original vote, resulting in slight gains for the CDU and AfD, and modest losses for the ruling coalition parties. The overall pecking order of major parties remained unchanged, with the SPD leading. The rerun, affecting around a fifth of Berlin constituencies, will not alter Chancellor Olaf Scholz's center-left coalition, but could impact the makeup of the Bundestag. The rerun served as a litmus test for the governing coalition's popularity, with concerns raised about the timing and logistical challenges of the rerun.
