Why did they choose a black actor to portray Obama?

It does bother me how people consider Obama to be black, or even african-american (african/american, more like) based solely on his appearance. Aside from that, he has absolutely nothing in common with the average african-american. Nor would he. His earlier life was more in line with what you might expect of a privileged 'white boy.' And he has no ancestral links in common with those descended from african slaves.

I do find it quite humorous when BO appropriates what harry reid would call a "negro dialect" tho. He does enjoy thinking of himself as a "brother" despite his polar opposite life experience. I recall the time he was filmed voting in chicago a few years back, when a real black guy joked with him about hitting on his girfliend or something. Barry busted out the street lingo like an old pro, and even threw in an "aight". What a goofball.

Corrections.....His an mulatto, not an black person
