Ben is probably one of THE worst choices you could come up with. He has NEVER run for nor held an elective office. He puts everyone to sleep, he's a stinking/GOD awful debater, knows NOTHING at all outside of medicine, and HELL NO...he would NOT attract black voters!
He may or may not be a "nice man", I don't know, I don't know him. What I DO know, unlike you, is politics.
Neither has Donald Trump.
