Turkey's Runoff Election: A Pivotal Moment for Erdogan's Reign.

Turkey is holding a presidential election runoff on Sunday between President Recep Tayyip Erdogan and opposition leader Kemal Kilicdaroglu. Erdogan exceeded expectations in the first round of voting, gaining 49.5% of the vote, but failed to secure a first-round victory. Kilicdaroglu received 44.9% of the vote. The winner will oversee serious domestic and international issues, including the country's economic crisis and NATO membership. The election is seen as a battle between Erdogan's 20-year authoritarian rule and the opposition's vow to restore parliamentary democracy. Polls open at 8 a.m. on Sunday and close at 5 p.m., with final results expected by Monday.
