Turkish Electoral system requires at least a simple majority for the presidency stage (50% + 1 vote) and seems like none of the candidates will be able to reach it (assuming the trend stays the same). This will result with an unclear 2 weeks when the elections (only for the presidency part, not the parliment) will have to repeat between the two most voted candidates (Erdogan and his opponent).
And the spoiler third candidate here is farther right than Erdoğan so basically a big waste of time for everyone while a run off election elects him again.
