Nationalist politician's rise threatens Erdogan's reelection chances.

Sinan Ogan, a far-right nationalist politician, may become the kingmaker in Turkey's presidential election runoff, potentially deciding President Erdogan's political fate. Ogan received 5.17% of the vote, enough to swing the runoff vote in favor of either of the candidates. Ogan has been critical of both Erdogan and Kilicdaroglu, but the majority of his voters are closer to Erdogan than his main rival. It is unclear if Ogan will set conditions for his support for either candidate, but his previous affiliations and political positions may give an indication as to how his backers may vote.
