The current Hokage, Tsunade, might die. If so that whole process skips. If not, then she will also approve of Sasuke. She will approve of anyone Naruto approves of and she has been shown to like Sasuke at least a little as shown by her delaying Sasuke being labeled as an enemy of the Leaf.
The Jonin will also approve of anyone who Naruo approves of. Current Jonin? Kakashi, Guy, Kurenai, some Anbu. Kakashi and Guy's word will be good enough for Sasuke to be approved.
The Feudal lord isn't very smart and easily swayed. Period.
And you act as though there aren't asspulls in this manga? Sakura storing 3 years of chakra and letting her village get destroyed instead of helping, comes to mind?
I am a sasuke fan myself but you are not making any sense.
Even if Tsunade dies, the decision goes to the elders.
We saw this during the jiraiya, then later Tsnade situation.
The elders are not big uchiha fans, already due to what the uchiha tried to do.
So on one hand, we have a candidate who is a previous hokage's son, but has become a hero even before the this war arc for his achievements against pein. With the war arc he has gained acknowledgement from every other village shinobi.
On another side we have somebody who left konoha to seek power from an enemy and later joined a criminal organisation. Not to forget attacked the kage summit and killed, danzo the one acting as hokage at that time.
Sasuke climbing this very first hurdle alone is unbelievable. As i said, it will be flat out nonsense if sasuke was to climb this very first hurdle, let alone the other 3.
The jonins will also pick naruto over sasuke regardless of what naruto wants. History will repeat itself, but also the jonins know that naruto is a better candidate and its been his wish from the very first chapter. Sasuke however two chapter ago he wants to be hokage.
Finally the feudal lord, isn't easily swayed and has advisers.
It is literally impossible for sasuke to become hokage.
Nd yh there has been many asspulls, but who said i am not complaining about them lol
