He insist that he is a christian, and not a Muslim. I think he is full of shit personally. Look at his record in the past couple of years and decide for yourself. I'm not saying that he is a Muslim, but I don't believe for a second that he is a christian.
Here is why:
1) He took National Day of Prayer out of the White House
2) He doesn't celebrate Easter
3) He celebrates Ramadan.
You can also add that when prayer is being said at a function he attends, he is either looking up or standing there with a stare on his face. He doesn't bow his head, or show that he is praying.
From those alone, what would it tell you?
