he would def choose konohamaru. it's almost impossible for sasuke to become hokage, even if he did get chosen by naruto. sasuke, even with his deeds thus far in this war is still a criminal. the whole good out way the bad doesn't really fly to well when you are talking about crimes, especially as he has killed people. i'm looking at those samurai he slaughtered in the land of iron. but i will say he will at the very least be brought back into the village and at the most may lend some "wisdom" to naruto after he becomes hokage.
@da best ever i have to disagree about sasuke knowing what it takes to be a great kage, i disagree big time. as a kage you have to know when you need to differ to people or ask for help, sasuke is not the type. he also doesn't realize that he not just gonna become hokage because he just decided to a few hours ago. as itachi said "those who are acknowledged are the ones who become hokage." sasuke doesn't care what other people think or really what they want, he would be terrible for the position.
on the other hand you have naruto who has shown that he cares about everyone, even as a kid vowed to change the practices of the hyuuga. then you have konohamaru who is basically his disciple. he will learn his ways from naruto just as naruto did from jiraiya. plus konohamaru has love for the village, sasuke was just gonna destroy it earlier that day. sasuke would be a horrible choice, thus naruto, even with him caring about sasuke knows this and would ultimately choose konohamaru. also the fact that naruto and sasuke are roughly the same age and will probably die around the same time. i mean who is really gonna be able to kill either of them once this war is over? so konohamaru will be slightly younger and more capable. although, konohamaru is not that much younger than him and ths will be old as well, unless naruto decides to let him become in earlier after he has been hokage 20 years or so.
