You can’t explain away the scar on his neck with your Magic Negro can’t brush his hair right theory.
Heh... I'm surprised that you remember that. Good memory.
To tell you the truth, I don't know what I'm seeing in that picture of the left side of Obama's neck. Seems that if he has a scar of those proportions on his neck, we'd have seen it long ago. We haven't, so I don't know what that is.
Could be some photographic gremlin for all I know. I'd like to see more pictures, to compare.
