The parliament has 14 days to try and get a different (or the same) person elected with the total majority (>50% of votes). If they can not get a person elected with more than 50% of the votes during those 2 weeks they then can elect a person with a relative majority. Since Merz was only short a couple votes they will probably still elect him and this was just a demonstration of power from the SPD since they barely have the 50% in the parliament if both parties combine their votes.

I think they are referring to Nazi Germany in and before WW2.

I’m unsure if they count as bugs but I got stung in the head by a wasp yesterday while it was 5°C and -2°C the night before. They can not be bothered.
