Nah, Shino dun have the people skills to be Hokage. And All Shika has is 1 skill. I know thats kinda speaking too early, what with Naruto failing the Genin entrance exam and everything, but when your at Chuunin level, and all you can do is bind shadows... Hokage isn't your line of work. Now, I forget his name, but the dude that is all scarred up, the Sadist. That could be Shikamaru's job.
