Actually he is. I think there was a episode in Naruto saying Hinata's dad is one of the strongest fighter in the whole Leaf village below the Hokage.Originally posted by: DB_Hunter
Kakashi is now way near the level of the current calibre of Hokage's... he needs to seriously train and get stronger if he is to be a contender for the title.
If Tsunade dies and Jiraiya still refuses to be Hokage, then perhaps one of the Hinata's dad will become Hokage... that is if he is stronger than Kakashi...
