Are we really being represented?

I feel very privileged to be able to be alive to see the first African American president. However, has President's Obama's presidency really broken down racial barriers? I think that it's easy to say yes because we are actually seeing it, but what is never mentioned is the resources that we "colored" people lack to be like President Obama. Moreover, I am speaking on behalf of all races when I say this: Are "colored" politicians really representing the needs of their "colored" constituency? Or do they appear to be representing the needs of "colored" people because of their appearance and have only become enculturated into the white dominant culture?
