Gül is on the same page with Erdogan, that would make no sense to make such a big risk for replacing Erdogan with someone very similar to him. I think this is a cout of the armees secularists and ataturkists to get rid of Erdogan but all in all they would have a hard time to succeed if they are not able to end the whole thing fast with a blitzkrieg tactic. The longer it lasts, Erdogans risho pashmoos will regroup, organize themselves and hit back and he has a lot fans like this.
