He write in the Introduction to this 2009 book, "(the book) tells the story of s__ scandals that have enveloped presidents and many other public notables. It does this by laying out the history of scandals from the country's earliest settlement to today... In doing so, the book reveals how the nature of scandal has changed over the four centuries since Europeans first settled the New World."
He then proceeds to detail (in summary form, and not in lurid detail) the failings of dozens of public figures---particularly politicians. He includes members of both Democratic and Republican parties. He is particularly indignant, however, over the "moral hypocrisy that underscored Republican attitudes toward sexuality and power." (Pg. 191-192)
He concludes with the suggestion that "In our new twenty-first century America, with a new president, Congress and historical reality, the role of the scandal will likely persist but have far less moral---and entertainment---sway over political and cultural life. Americans have too many important issues to deal with." (Pg. 218)
This book is by far the most comprehensive I have ever seen, in terms of being a compendium of such scandals. While not exactly "inspirational reading," if such a compendium is what you are looking for, this will be "must reading."
Politicians are human and have all of the same human flaws. "Sex Scandal America: Politics & the Ritual of Public Shaming" goes over the history of the United States and its flawed politicians from even before the United States existed, with the not-so-pure Puritans. Over the years, sex scandles have changed from cause to hang someone to merely fodder for the likes of Jay Leno. "Sex Scandal America" is a spicy look about how scandals and American culture have changed over the years.
