I guess that's the thing: from what I can tell, Turkey ceased being a democracy with Erdogan. I do not believe anything pertaining to votes in Turkey for some time, since the time Erdogan was first elected. That vote was suspect, and so has everything that's happened since then.
In certain ways, what I find so disturbing about what's been happening in Turkey is how readily everyone seems to accept the official account of major events. The vote that initially established him, the "coup," the most recent vote... Things seem to be accepted at face value by the west without questioning it, even when major red flags are everywhere.
Erdogan isn't just a despot, he's a liar. And the West, especially Western journalism, seems to turn a blind eye.
Even if a large proportion of Turkey supports Erdogan, it doesn't mean a majority do. Even if Erdogan's government says a majority does, doesn't mean it actually does. And when a government establishes itself by subverting democratic or constitutional processes, it's not a democratic government anymore.
But as Merkel put it : erdogan is a democrat in a democracy.
Nothing we can do here.
