Barack is biracial and his father isn't even African American. He himself said his grandmother, who mostly raised him iirc, was a "typical white person", we all know what that means. In addition to all this he grew up in non black environments. I don't think these facts make him "less black" it just means he didn't have the typical black american experience growing up. I have people in my family who are 100% african american who didn't grow up with a typical black american experience. We aren't a monolith
One thing is for sure and that's that racist CAC consider Obama and that's all that matters really.
