All the childhood photos (with the exception of a couple photoshopped with other children in Indonesia) show the same kid growing up in my opinion. Starting with the high school pictures, it looks like a different person to me.
You are exactly right. this has been discussed before when someone posted the story about the guy in Hawaii with a picture of himself and Obama when they were eight and the Honolulu Star published it and the story. The kid was not Obama, I swear.
The kid in the middle photograph on his grandad’s back in the surf is NOT Obama. He’s the same kid as in the Honolulu Star photo but it is not Obama. Different face (chunkier), different teeth, different and darker color. This is so wierd.
Notice that there are never babypictures of little Barack with his dad when the family was supposed to be together before Barack Sr. left for Harvard. This is really odd.
