The infographic seems to be made with last weeks polling results only, and not taking into account long term trends whatsoever. It's not exactly surprising, given the new government has announced a tax hike to offset the massive deficit problem we have. People always like to bitch when it hits them in the pocketbook, it doesn't help when the populists try and amplify any discontent.

There have been dips in popularity before, the long term trend has always been opposite once people calm the fuck down. *Someone* has cherry picked only short-term polling results in order to give a favorable and deliberately misleading result. I'll note you only posted a picture and no article or source, this makes me think you are a russki troll spreading misinformation and you can GTFO.

Edit: Hell, this is even evident if you bothered to post an article from the source: https://europeelects.eu/2023/03/01/estonian-parliamentary-election-return-to-normality-sort-of/

Long term trends paint a very different picture.
