cumhurbaşkanlığını
"The presidency."
The word 'cumhurbaşkanlığını' is in the accusative case here, indicating it's the object of the verb 'kazanma başarısını elde etti' (achieved the success of winning), representing the position of the presidency.
O, cumhurbaşkanlığını kazanma başarısını elde etti.
He achieved the success of winning the presidency.
In this sentence, 'cumhurbaşkanlığını' remains in the accusative case, used as the direct object of the action 'devretme' (hand over), related to the act of transfer of the presidency.
Cumhurbaşkanlığını devretme zamanı geldi.
The time has come to hand over the presidency.
Here, the term 'cumhurbaşkanlığını' still appears as an accusative noun form, but it is part of the phrase that provides context to the verb 'kazandıktan sonra' (after winning), again referring to the role of the presidency as the focal point of the winning action.
