I feel that the SPO was caught in a dead if you do and a dead if you don't the situation.
Looking at it, they could either leave Kurz to use his political position during the election or take him out but face the wrath of the electorate.
I still think that jumping on the VONC was the better choice for SPO.
Anyway, it's clear that the SPO needs to do some self-reflecting after they inevitably lose to Kurz again.
To be clear though, I do not think Kurz should have been VONC'd as the resignation of Strache was more than enough.
