Obama's contribution to racial disharmony

Jack Cashill is an investigative journalist unknown to most of America.  Unknown because he is fearless and mostly takes on controversial subjects and topics, like Obama's birth certificate, subjects that MSM won't touch with ten foot poles.  In this investigative piece he explores Obama's "contribution" to racial disharmony in this country.  For anyone familiar with the Trayvon-Zimmerman murder trial what Cashill has to say about that and other racial events is sadly revealing.  Obama is a one-man political wrecking machine who does and will do anything to secure his base of voters.  If that means stirring up racial animosity between blacks and whites, well that's too bad, must keep the 95% support of the black voting bloc on the plantation.  This is a very cynical and I believe, accurate view of what motivates this strange person who is the president of the United States.
