Hopefully, with PiS' guy still as President, not to mention lots and lots of seats in the parliament still held by PiS, not much progressive legislation will get through. That said, for all the anti-immigant rhetoric of PiS over the past few years, they're responsible for opening the doors to the africans I see out and about in small-town Poland. I can't see much changing - a continuation of neoliberalism on a much smaller scale than Western Europe.
With the exception of abortions, even self-proclaimed 'liberal' Poles aren't liberal by Anglosphere standards. The idea that anyone can be Polish for example is not even a concept.
On a positive note, at least Konfederacja increased their seats too.
