Any references to this besides the math of Arthur Anderson?"The Delaware senator and his wife, Jill, showed annual earnings of more than $200,000 and sometimes $300,000 between 1998 and 2007. And they gave relatively very little of it away. In 2007, their most generous year, the Bidens gave $995 to charity. In 1999, their charitable donations added up to $120."
Maybe this is why, i.e. he needs to pay what he ows first, like someone who's fiscally responsible?

Frankly my concern is that he has no convictions, indictments, or sealed documents down at the court house.
I really enjoyed this one though:
