———It seems President Obama is the first male in his line not to be a polygamist. ——
Except that in modern America polygamy is replaced in urban black society by promiscuity. Promiscuity practicers don’t get married and have their babies raised by grandmothers or aborted. The fact is, America doesn’t know the magnitude of Obama black societal promiscuity and how many Jesse Jackson like fathered bastards are floating around Cambridge or Chicago.
Also, as suggested in post 10, the 'polygamy' of 0bama in and around Cambridge or Chicago may not have been of the procreative type.
Obama has been an “urban polygamist” as a homosexual.
