Recep Tayyip Erdogan's ugly win in Sunday's referendum on a new, authoritarian constitution for Turkey creates big problems for the country's secular democratic forces and for Turkey's Western allies — but also for Erdogan himself. His victory was not convincing, as he had hoped, but narrow, contested and tainted by the finding of a European observer mission that the pre-election campaign was not free or fair. Turkey's three biggest cities voted against the would-be strongman. The country is not united behind him, but polarized — a political reality that even an empowered ruler will ignore at his peril.
To be sure, the Turkish president sounded defiant in the wake of his victory, dismissing Western critics for their "crusader mentality" and hinting that he would embrace harsh new measures, such as reinstituting the death penalty — something that would surely rupture Turkey's relations with European Union leaders. As it is, Erdogan's government has purged some 130,000 people from their jobs and jailed more than 45,000 since a failed military coup last summer. The new constitution, which will take full effect in 2019, could allow him to remain president until at least 2029, with only weak parliamentary checks and a judiciary he could shape with his own appointments.
