Obama is regarded as Muslim by the Muslim world.

Sheppard Smith, Fox News. "If you check President Obama's last trip over-seas, his wife left just after their visit to France. She has yet to accompany him to any Arab
country. Think about it. Why is Michelle returning to the states when'official'trips to foreign countries generally include the First Lady."
Here's one observer's thought on the matter.While in a Blockbuster renting videos I came across a video called "Obama".There were two men standing next to me and we talked about President Obama.These guys were Arabs, so I asked them why they thought Michele Obama headed home following the President's recent visit to France instead of traveling on to Saudi Arabia and Turkey with her husband. They told me she could not go to Saudi Arabia, Turkey or Iraq. I said "Why not?, Laura Bush went to Saudi Arabia, Turkey and Dubai." They said that Obama is a Muslim and therefore he is not allowed to bring his wife into countries that adhere to Sharia Law.Two points of interest here: 1) I thought it interesting that two American Arabs at Blockbuster believe that our President is a Muslim, 2)who follows a strict Islamic creed. They also said that's the reason he bowed to the King of Saudi Arabia. It was a signal to the Muslim world, acknowledging his religion.
For further consideration, here is a response from Dr. Jim Murk, a Middle Eastern Scholar and expert on Islam. This is his explanation of what the Arab Americans were saying. "An orthodox Muslim man would never take his wife on a politically oriented trip to any nation which practices Sharia law, particularly Saudi Arabia where the Wahhabi sect is dominant. This is true and it is why Obama left Michelle in Europe. She will stay home when he visits Arab countries. He knows Muslim protocol; this includes, bowing to the Saudi King. Obama is regarded as a Muslim in the Arab world, because he was born to a Muslim father; he acknowledged his Muslim faith with George Stephanopoulus. Note that he downplays his involvement with Christianity, by not publicly joining a Christian church in D.C. and occasionally attending the chapel for services at Camp David. He also played down the fact that America is a Christian country and said, unbelievably, that it was one of the largest Muslim nations in the world, which is nonsense. He has publicly taken the side of the Palestinians in the conflict with Israel and he ignored the National Day of Prayer, something no other President has ever done. He is
bad news! He conceals his true faith to the detriment of the American people." --- Jim Murk, Doctor of Philosophy in Middle Eastern Culture &Religion.
