This is a very powerful quote. It is too bad that it was first published[1] 12 years after Erlichman told it to Baum and after Erlichman died. It sure fits with what I think Nixon was capable of, but I wonder how embellished the actual quote given by Baum so many years after Ehrlichman said it. Would have been nice to have Ehrlichman confirm it but he was already dead when this quote was published.
