To add further context: in 2021, Berlin residents voted in a Volksentscheid on whether the government should compulsorily purchase back housing stock from large private real-estate companies. The proposal received 58% support, but the CDU/SPD coalition in office at the time just ignored it. This now at least partially reflects in the votes. https://de.wikipedia.org/wiki/Volksentscheid_%E2%80%9EDeutsc...
