An invited book review DAVID E. KYVIG. The Age of Impeachment: American Constitutional Culture Since 1960. Lawrence: University Press of Kansas, 2008. 500 pp. $34.95 (cloth). Impeachment, not completely democratic as a true action of the populace and not entirely akin to a coup, is the instrument used by elected representatives to remove federal governmental officials for the higher purpose of preserving the polity. David E. Kyvig's new book chronicles the evolution of impeachment from the mid-1960's to the present. Although the chapters on Nixon and Clinton will leave readers seeking a more detailed discussion about these seminal events, and excluding chapters focused on impeachment's cultural impact, Kyvig's book produces a good overview of the events covered and succeeds in consolidating disparate impeachment events into a singular volume, thereby assisting future researchers in gaining an overall impression of the historical facts surrounding the use of impeachment. Readers seeking detailed narratives concerning specific impeachment episodes will need to refer to existing sources providing original exposition.
