On Sunday, Turkish voters face a stark choice between two front-runners offering drastically different visions for the country in an election that has grave implications not just for the future of Turkish democracy, but some of the most pressing global issues today. As the Turkish republic marks its centenary this year, President Recep Tayyip Erdoğan, who has clung to power for an unprecedented 21 years, faces the challenge of convincing voters to cast his name at the ballot box yet again despite growing public anger over a cost of living crisis and the devastation of twin earthquakes in February that killed at least 50,000 people—and displaced another 3 million.
