This is harder than I thought. You cant directly delete the account, but you have to deactivate it and it is then deleted automatically after 30 days (IIRC) if and only if you dont login during that period. This can be problematic, if you have many devices and borwsers with a million open tabs :/

Not really, this was expected. Ex-Kanzler Scholz is quite unpopular in Germany currently and after the failure of the last administration it was expected that many SPD-Voters will vote CDU
