Erdogan's Political Future Hangs in the Balance as Turkey Heads to the Polls.

Turkish President Erdogan faces a tough battle for re-election against a united opposition led by Kemal Kilicdaroglu. Most polls show Erdogan trailing his secular rival by a few points, and Kilicdaroglu is trying to break the 50-percent threshold to avoid a runoff. Erdogan has pledged to respect the vote if he loses, but tensions are high, and there are fears over what he would do if he lost a narrow vote. The election takes place amid Turkey's economic meltdown and a crackdown on civil liberties during Erdogan's second decade of rule.
