I am not concerned that he will try to run for a third term. My guess is that he sees the presidency as a stepping stone to either SCOTUS, where he could be the Real Black On The Court, or Secretary-General of the UN, where he could be the Savior of the World.
SCOTUS... if Hillary wins and would appoint him. Possible.
UN Secretary—Not possible as I understand the rules—citizens of Permanent Security Council members are not eligible. Of course, you could say that rules are made to be broken or changed.
Secretary-General of the UN, where he could be the Savior of the World.
Wouldn’t be surprised to see that happen
