I'm back from a "walk" of my nearest commissions (in fact I only went to see mine, but they were still counting, so I made a little tour). It seems that our Olympic champion Szymon Ziółkowski will remain in the parlament as he gets third score on the KO's list in these six commissions (and they should get 5-7 seats). Of course, it's just six commissions in a city being almost a suburb (a big one in fact, but still) of a third biggest town in Poland, but I don't think our way of thinking is far from the Poznanian one. Maybe the thing that might work in favour of Ziółkowski in Swarzędz is the fact he lives here for three years (what I got to know just during the campaign) and he had quite a few posters in the city (including really big ones).
To add something to VolleyRuller96's summary: PiS is national-socialistic party, though it is controversial to call any party this way. The exit poll says 239 seats - with so many social programs they set during last four years, spending public money on, as it is said, "buying votes" they have just 4 seats more than in 2015. That's really poor and Kaczyński seems to have understood that finally, that it's not half of country with him, but half of country against him. At least that's what he said, for the first time I think. And he looked a little bit sick/drugged, but maybe that's just my impression - he is quite an old man.
KO needs a change - with combining PO, .N, Greens and some other liberals they lose 8 seats comparing to the result of PO alone last time (adding to that 28 seats on .N - that's a lot). The leader Schetyna is not a leader, he's an anchor. And he seems to understand it - he even didn't want to be a prime minister (which was a great surprise, knowing his ego). Their only program is being anti-PiS, which would be enough in a more democraticly advanced country. And they seem to have no candidate for the presidential election next spring.
Left - an alliance of three parties - post-comune SLD, Wiosna, whose leader is a gay, and Razem, which seems to be most far left of this trio. Wise, clever people, indeed, but we're not very leftist nation. Still was hoping for them to have about 15%.
PSL-Kukiz - if Kukiz loses his rebel, punk ideas, becomes more diplomatic, he might create with them a new centre party. PSL's reputation is simply a whore - they'd go with everyone. 10% is their best result since... I remember probably (excluding local elections, when they usually have good result).
Konfederacja - far-right, but with such a little result, they won't have a lot to say - rather a trivia in the parlament. Their presence has two good sides - firstly, they will take some seats from the other parties, mostly PiS, secondly, they're more right than PiS and the only economically right party, so they might take some voters from PiS in the next four years (which then becomes a little bit dangerous).
Exit polls/late polls (surprisingly very little change) might be a little bit overestimated for PiS, if not with percentage, then with the seats. Except of PSL-Kukiz they have no one to go to alliance with and alliance with PiS might be something what even this green whore wouldn't do. What's more - opposition has no way to became an alliance as Left and Konfederacja are on the other poles of the Earth. But they might block something together.
