The Big O is a total failure. He has created the worst race relations in America since the 1968 race riots.
Calling Obama a failure, presupposes that what you describe was not his original intention. But reviewing the mentors of his youth, his 20 years in Rev. Wright’s congregation, and his work as a “Community Organizer,” in a community where he had no actual roots; the assumption should be that he achieved precisely what he intended.
Except that every day he does something to encourage voters to elect Trump.
Because of the access to social media, I believe it to be far worse now.
