Authenticity, the dominant cultural value of the baby boom generation, became central to presidential campaigns in the late 20th century.

In the process, they rewrote the political playbook, redefined presidentiality, and changed the terms of the national political discourse. This book is predicated on the assumption that it is worth knowing why.
