Definitely looks like a new poll will be happening. Not sure what they expect the outcome to be, though. I think the changes will be negligible, probably slightly more votes for AfD/FDP but not enough to matter.
No one knows where the shit-show is heading right now.
SPD doesn't want to form a coalition with CDU - they repeated that several times.
„Jamaica (CDU/FDP/Grüne)“ is not going to happen.
It'd be our end if something like CDU/SPD/Grüne probably happened. Fuck.
Another option would be a minority government, although Merkel insists that she will do everything to prevent that.
In short: Fuck knows.
