This book, written by history professor Robert Dallek, provides an overview of the administrations of American Presidents from Theodore Roosevelt to Ronald Reagan. If you're aware of their accomplishments, or failures, you won't find any earth-shaking revelations in this book. The author is non-partisan, and offers thoughts as to why some achieved greatness, and why others came up short. All in all, it serves as a nice review of the times, but won't reveal many new insights. ( )
