12 years is a long time in prison.  Especially if, like Paul Manafort, you’re 68 years old.  If you put together the pieces here, Robert Mueller has given the former Trump campaign chairman a stark choice.  Cooperate or possibly spend your golden years in big house.  It’s obvious Mueller thinks Manafort knows more than he’s letting on.  So, released from prison when you’re 80?  Dying in prison?  Strong incentive indeed.  Bloomberg lays out the case.
