Ding! They will continue to point out the the vote was 'illegal' whatever the hell that means. These people asked for this for years, Madrid kept saying 'NO' because they knew the outcome and they couldn't rig it like they did Scotland and so many others.
You do realize that Berlin's results last week were likely tampered with and AfD likely had more like 16 or 18% of the vote. But at that level Merkel wouldn't have been able to cobble together any coalition... so, they delayed results for hours and screwed with the results just like they did in the regional by-elections in May.
Merkel could easily wind up in jail in the next 18 months for election fraud. And, if the EU begins to splinter she will be thrown under the bus by the 'elites.'
