So her resignation basically doesn't matter and was entirely a publicity stunt because the Green party got upset that the "far right" got anything even slightly done it's way even once.

If she gets voted in again, a majority needs to say yes. The fact that she came in at all was because of a technicality reversing the vote so that a majority must say no. 49.7% voted no to Magdalena as the new PM, only 33% voted yes.

She could try again, but she won't get majority support. And even if she does, she'll have to rule with the environmentalist party as opposition, meaning the environmentalists can stop many of the governments bills from ever happening.

I just want to also draw attention to the phrase "far right". It's used because it's easy to defend it's literal meaning- "far" is a relative term, so it basically includes half the planet- but it evokes the imagery of fascists and nazis. So you get to call your opponents nazis without having to ever have to defend yourself. "Alt right" is basically the same thing, except even more vaguely defined. This is probably obvious to anyone who stops and thinks about it, but it's worth stating explicitly.

This is one of the reasons the left is falling rapidly in Sweden for every election, people are sick of the BS, and "the right" (if you can call them that) simply avoid going down that trap and behave like adults. Which is actually impressive as the fake news moderators in debates always encourage the left to cry nazi or reeeeysist, they want the opposition to take the bait and sink to the same childish level as them.
