Nope. Barack Obama is still a practising Muslim.
His verbal slips - “...my Muslim faith... - and actions - his book ‘Audacity of Hope’ is titled in Indonesian, ‘Jihad: From Jakarta To The White House’ - hardly the book title of a Christian - and then there is that bow to King Abdullah of Saudi Arabia.
During the 80s all his college roommates were Muslim. And then there is the puzzling absence of college admission forms. There is no evidence he returned to the U.S. in September 1981 to attend Columbia.
The reason I bring this last part up is because no one who was taking the same classes he should have been taking then remembers him. But that would certainly be the case if he started at Columbia in January, 1982, rather than September 1981. So why is this important? The Hajj at Mecca occurred in October of 1981. He was in Pakistan visiting with people who were officials in the Pakistani government. So close to Arabia - well, why not go on pilgrimage!
I doubt he will ever admit it, but I think he is a devout Muslim and hiding it. He sure dislikes Israel.
Maybe he was getting study-abroad credit from Prof. Brzezinski.
