President Johnson may have been the most effective practitioner of the kind of one-on-one persuasion and bargaining that Richard Neustadt believed was the foundation of a successful presidency.
Fortunately for us, LBJ recorded many of the phone calls he made as president, and it's possible to actually listen to him work his way through the process of persuading people to do what he want. National Public Radio did a stroy about LBJ's tapes, which you can listen to here. (If you pay attention to the story, you can hear echoes of Richard Neustadt throughout with constant references to persuaision and bargaining.)
