A bit soon to tell, but it’s quite unclear what will happen. I don’t find believable the article blaming cultural issues for the changes though, or UP’s “messianic” ministers.

I think the issues are economic. Inflation has made many people angry and uncertain, and the same for increased interest rates. It’s not as bad as in much of EU, but arguably there was less disposable income too. Whether the left can regain the initiative remains to be seen.
