Now we know that Vito had says to Mike later on that " I never wanted this for you." But yet Clemenza tells Kay that Vito thought Mike the best to take over the family business.
I don't think that's a contradiction. People in charge of a family, corporation, business, etc... all have the same "traits" if you want to call it that. They pretty much all have to do the same thing. IMO Vito sees these in Michael and says yes Mike would be the best to take over this family but he also has the skills to be Senator etc..
