Since we don't have any real results yet, I thought I'd go back in time a bit and also try out the new municipal election format somewhere outside Sweden for a change.
In 1919, Berlin held its first-ever municipal elections under universal suffrage. For all its history up until that point, the City Council (known in German by the very handy term
Stadtverordnetenversammlung) had been elected by the usual Prussian three-class electoral system, which gave a few hundred very rich voters equal weight to the poorest 80% or so of the city. Although turnout was always low, the SPD had a near-monopoly on the votes in the third class, so everyone assumed the city would go very deep red once the class distinction was abolished. But of course, by this point the SPD was splitting wide open, and both factions had some sway in different parts of Berlin - the majority SPD was strong in the city centre and the southern suburbs, while the USPD got the loyalty of the Wedding party organisation and quite a few of the north and east suburbs.
The election saw quite a low turnout once again, only 57,6%, likely because the National Assembly and Prussian Landtag elections had both been held quite recently and people were fed up with voting. The result saw the SPD and USPD on almost exactly equal voteshares, the latter edging out the former by a single seat. Put together, the two parties reached nearly two-thirds of the vote, with the remainder split between the four bourgeois parties now emerging - the DDP, the successor of the old left-liberals who had always dominated the higher classes in Berlin, only achieved a narrow third place ahead of the conservative DNVP, and over the next decade they'd only continue to shrink.
