Kakaschi easely!
Naruto isn`t ready yet, way to young and inexperiant!
Kakaschi has enough experians, power and knowlege and maybe the most important respect
I agree.
1. Remember that they are currently at war. Tsunade is not in the condition to be out on the battlefield. Now shes more like the 3rd Hokage.
2. Shikamaru even knows that Kakashi is a reliable leader.
3. When ever decisions have to be made on the fly, inside the village, or outside on a mission... all the other Jounins go to him for their orders.
4. Most importantly... Now that Danzo isn't influencing the decision of the feudal lord and konoha elders... their original decision to choose Kakashi will finally happen.
** But what does that mean for Naruto? Hopefully he has complete control of the Kyuubi now. Also, that Yamato will be nearby if necessary.
* I think that Madara's goal is to make Naruto feel alone, and force Naruto to seek isolation from all of his friends, to get him all by himself and vulnerable. Because if Madara is anything like Danzo, then we know that they are manipulating everyones thoughts...
Kakashi never dreamt of becoming hokage, nor would he actually manage to keep up with the war. Hes kinda lazy

And he have no previous hokage experience.
Other than Danzo, the Hokage has been chosen naturally. It is a person whose name is known for its greatness is some way.
Tsunade didn't choose to be Hokage. The 3rd or 4th probably didn't choose to be Hokage. Neither will Kakashi when its his turn.
