It could also be because this election result is hard to de-cypher. The process is totally alien to the British (FPTP) or US ways of running an election: nobody can tell for sure who will be chancellor as the outcome will only be apparent after several months of negotiations, so speculations at this stage on the consequences/outcome are necessarily muted. The Greens and FDP are both in a kingmaker sort of position, but are sharply divided on key issues such as taxation.
And this is how it should be: where votes matter and compel compromise.
