Obama was the president (one of the best) of the US. He wasn't the president of Black people, Democrats, Africans or Luos. By the way, have some respect for Luos. But, by all means, what were you expecting him to do (specifically) for them or for his step-brothers? Being a president doesn't mean that you can perform miracles. Or, did you expect him to do what your buddy Trump is doing by cutting deals with his friends and pardoning his criminal friends? Obama was/is an honorable man, and he did his job very well.
