naruto not smart ? lol.He can. He has the overwhelming support of the people. He's incredibly powerful and people follow him. Sure, he's not smart, but neither is the Raikage. He has Shikamaru to advise him.
1. naruto and emo? show me emotional decision 2.naruto and chuunin exam? this been very unfair to naruto. 3. kakashi not beeen good hokageEven hokage have advisers, and Shikamaru Nara will be right there with him.
Naruto has a different kind of genius; he doesn't have much cognitive genius, but he has tons of emotional and creative genius.
If Tsunade dies/retires, the Jounin would probably elect Kakashi (again) first. Naruto has to wait another half year to take the Chuunin exams, then impress the Jounin so they can vote to add him to the Jounin council.
