I don't think these local elections reflect the national mood. Actually they never do, because local issues dominate. Look at the number of big cities where the independent city presidents renewed their mandate. Also 17% for PSL....that does not reflect their votes in national elections.
Myself I voted here in Warsaw Bielany for a local party which focuses on local problems. For all other positions I voted Green, because I do think PO and HGW could do a much better job - look how they handle the reprivatisation (not to speak of the controversy her husband finds himself in regarding this matter), but also didn't want to vote for these PIS morons, so I decided just to be cross.

PO loses in favor of PiS and local committees - in this way the elections to the district councils can be briefly summarized. But in any part of the Warsaw situation is slightly different. The balance of power in the districts of Warsaw will change. Until now only 18 districts in the three are not ruled by PO. Now the platform will certainly rule in eight, PiS certainly in the three (so far only had one). In the remaining seven the situation is not yet clear, the alliances shall be decided by the local committees.

If you see the results in Warsaw, it is clear that in quite a few districts local committees are getting a lot of votes, which I think is really great. They know the local issues and problems.
