On the birth certificate, Obama’s father is listed as “black”. But in those days the term “negro” was generally used on official documents.
I’d like to see a study of Hawaii birth certificates of negro/black people born in Honolulu from 6 months before Obama to 6 months after Obama to see how many were listed as “black” and how many were listed as “negro”. I’d guess almost all would be listed as “negro”.
I think Hawaii is a far-left state and the Democrats who run it would not allow such a study.
