A photo of Barack Obama in Muslim garb has been published by the supermarket tabloid, the National Examiner. This is not the same tab that published pictures of George W. Bush shaking hands with space aliens, as I recall, but I am not entirely certain I believe that the photo is genuine. Sweetness & Light posts a copy of the picture for all to see.
On the other hand, it is not unusual for tourists and visiting dignitaries alike to don local garb when overseas. I have worn some fairly ridiculous outfits myself while in places like Northern Thailand and Egypt. President Bush has been seen in some outfits handed to him at summit talks, and the photos plastered all over the front pages of the nation's left wing dailies, to general hilarity among the smart set.
Which raises the question of why this get-up, assuming it is a genuine photo, has not been more widely distributed. It didn't make it into the adulatory documentary movie made about Obama's visit to his father's native land. I anxiously await the verdict of photo analysts able to detect PhotoShopped pictures.
