Yes, budget. From the information we know naruto isn't really the smartest person. It may not take alot be he isn't patient either. His clones yes would come in handy in manpower but Naruto's not the type to be calm and think rationally in a intense situation. It's been proven. His emotions guiding his words, thats a bad thing as to being Hokage. Both Tsunade and Raikage might respect but it doesn't mean it's a requirement to become Hokage.
Naruto has matured a fair deal over the course of the series. Ay hasn't exactly been shown to be a genius either. In any event, intelligence is completely and utterly irrelevant. Naruto has Kurama, who is intelligent, and centuries old (=experience).
He has the respect of all of the other Kages, and also of the entire shinobi world. He was pretty much the de facto leader of the Shinobi Alliance after Madara showed up, and before the four Hokages arrived. The entire world views him as a hero, and the villagers themselves stated, after the Pain attack, that Naruto "should be Hokage".
Sasuke doesn't only understand the hate specific to him he also knows the history that has been repeated in the village. Naruto only urged Sasuke not to take revenge because he knew it was wrong and because he didn't want him to be consumed by darkness. Naruto never understood Sasuke's pain. Sasuke didn't change cause of Naruto he changed cause of Itachi and what Hashirama said to him. You're right about Naruto understanding how to create peace. But Sasuke understands what needs to be done to save the village from a repeat of bloodshed and hate. Jiraiya didn't leave Hokage for him. He left him to find a way that all shinobi understand eachother, a way to find peace. Not Hokage.
Naruto didn't understand Sasuke's pain? The dude was ostracised from society his entire life for no fault of his own. He didn't even know why everyone hated him. To top this off, he lived alone, his entire life, in a crappy apartment and the only real friends he ever had were Teuchi and Hiruzen. Everyone else either downright hated him, or simply avoided him. I'm sorry, but Sasuke's pain is nothing compared to Naruto's. The "you were always alone" is complete bullshit.
Anyway, everything you said justifies Sasuke becoming Naruto's right hand man, not becoming Hokage.
Sasuke has made mistakes but he has helped more that he hurt, even if it was unintentionally. Sasuke never said sorry for the things he has done and he never said he would make it up to anyone. He wants to only protect the thing his brother died for and follow his brothers will. Sasuke bears the hatred of his whole clan but he's putting it aside for his brother.
You're falling into a broken window fallacy. None of Sasuke's actions so far have been intended to help Konoha or the Shinobi Alliance. His criminal record is huge.
But if we put it in terms of Naruto as Hashirama and Sasuke as Madara. Well Madara told Hashirama that one day the Uchiha's will be annihilated and he wanted to become Hokage to change that. But instead Hashirama did and what Madara foretold actually came true. Madara truly cared for the village and his people, he seen the hate festering and wanted to stop it. But he didn't have the chance as for no one wanted him to be Hokage except Hashirama. But in the end Madara did know what was best and Hashirama failed. Later Madara became corrupted but before that his ideals were what the village needed and the village didn't want to accept him just like Sasuke. What the village needs is Sasuke.
Even the Uchihas voted for Hashirama. The same thing would happen now. NOBODY would vote for Sasuke. He's an S-Rank international criminal. And Naruto is the hero of Konoha, and the Saviour of this World.
The position is pretty much there for him to take at this point. Tsunade's death = Rokudaime Hokage Naruto Uzumaki.
The Uchiha Clan Massacre was a terrible crime on Hiruzen's part. Nothing justifies the genocide of an entire clan, no matter what.
But still, it was an Uchiha (Obito) that changed the village's impression of the clan (strong, elite, loyal). So... In any event, the village > Madara. Madara would probably have done better in terms of the Uchiha clan, but what about the rest of the village? Like Tobirama said, Hashirama was the visionary. It was his plan, his ambition that created the village system. Madara should have stayed in the village as Hashirama's right hand man, and become the Second Hokage after Hashirama died.
Madara, despite having lost a lot of his clan's respect, was still Clan Head. He had Hashirama's backing. He could have easily gained back his reputation, and challenged Tobirama for the seat of Hokage. Furthermore, as Hashirama's right hand man, he would have had a big say in internal and foreign policy.
