0bama attended a madrassa in Indonesia, he never went to any school (that we know of) in Kenya.
0bama bowed to the King of Saudi Arabia, among others, Egypt has a president and a prime minister.
Were he a Muslim that would not preclude his being POTUS unless the 1st Amendment has a loophole I'm not familiar with. And he did take the oath on, I believe, Lincoln's Bible. Is he a Marxist? Probably, and that's where the concentration should be.
