What is your vote though? And why would it be a concern for democracy?
It is still people who is going to elect the state of authority "Baskan", and there will still be a Parliament and members of parliament.
As long as people gets to vote - I don't see any problem in the new constitution. Surely the state of authority will possess more power and abilities - but that's all the point, that's how to keep the state more dynamic and have a stronger political entity. We already suffered many coalition governments and coups, this new constitution will be a great barrier to such obstacles and suffocations. I urge strongly for you to vote "EVET", you're a reasonable Kemalist, you should see that this is much more favorable for Turkish future. I don't understand why people jump in the hype-train of fearing and hating Erdogan - which mostly derived from western media and FETÖ propaganda.
FETÖ votes "Hayir"
PKK and its tails votes "Hayir"
Germany, Holland, Austria and most of Europe favors "Hayir"
All sorts of anti Turkey and anti Turkish agendas favors "Hayir" actively worldwide.
Because a "Hayir" simply puts chains into the dynamics of the state, and if I was Germany or Holland - I wouldn't want an independent strong Muslim Turkey.
Simply use your mind.
