"this from the guy who has never successfully explained how he persuaded a mobster to loan him nearly a million dollars so he could buy the vacant lot next door to his mansion?"
Oh, you make it sound so unsavory.
I would say that he has successfully explained all that he needs to explain at this point, to the satisfaction of the Democratic nominating process anyway, if not to yours. You may wish the question would resurface on your terms, but it's not likely to, no matter how often you post it.
