So, a bit of #anlysis here, but, despite the well publicised struggles in Austria and Sweden; various Green parties are doing well across Benelux, Germany, Switzerland; which means they are polling well in pretty much all of their traditional "heartland" except for Austria.
What the heck happened to the Austrian Greens?
Botched factional party games resulted in a split, a collapse in support and an electoral disaster. Voters respond to what they have on offer in front of them, elections are not natural phenomena that we measure.
