You’re giving Baraq way too much credit for being ambitious.
All he wants to do is collect a huge take in POTUS pardons and live like a potentate for the next 40 years. With occasional adoration sessions on Blowprah, MSNBC, and BET.
He wants, and/or his handlers want him, to be Secretary-General of the United Nations. I would expect that he is in the process of getting all his chits lined up now.
