The farcically inept "coup attempt" last year was AK's equivalent of the Reichstag fire - in which it may itself well have had a concealed hand in provoking, and that it now cravenly uses as an excuse for all sorts of abuses.
.
That isn't, however, where the present problems started.
.
AK has always been authoritarian.
.
But the urgency came with the electoral results that nearly toppled AK.  Turkey almost escaped from AK.  So they cynically prevented a government from being formed that would have excluded AK (and that would have brought the Kurds into the mainstream of Turkish politicals), and ran a second election to undo the results of the first election without letting an alternative government be formed.
.
Since then, AK has been working overtime to eliminate Turkish democracy.
.
If you think AK is going to allow any election results to be announced in 2019 that would remove Erdogan from power, then you probably don't know how to spell "Mugabe", either.
.
Never going to happen.
