The book really focuses on a few of the major political families of the United States: Washington, Adams, Lincoln, Roosevelt, Kennedy, and Bush. His chapters on Washington and Lincoln are insightful and interesting, but I found no new material or analysis on the Kennedys or Roosevelts. In the first appendix, which is about 100 pages or so, with a brief biography about every parent (and some step parents) of the presidents. There were typos, grammatical errors, and utter mistakes within its pages that should have been edited. Though I was impressed at times with the book, I ended up being disappointed at the amount of errors I found, especially in the biographies of recent presidential parents.
