Erdogan’s Muslim Brotherhood party (AKP) lost the Istanbul mayoral election.
The CHP has its roots in the secular government policies of Ataturk…the supporters sometimes called the Kemalists (after Mustafa Kemal Ataturk). My experience is that they lean both left and right but want to keep Islam out of the government. They would support the government protecting Islamic heritage but not forcing it or allowing it to dictate laws.
In contrast, the AKP supports a theocracy hidden behind western suits and ties and economic policies.
Istanbul … not Constantinople
