This book, claims author Rick Reilly, is not political -- it is about sports and his love of golf, a game of honor. When he read the ludicrous claim that Donald Trump had won 18 club championships, it inspired this book. The president is an excellent golfer and an engaging partner (as Reilly knows first-hand), yet is widely known for cheating and wild claims because "everyone does it" and "it sounds better." Much of Trump's life -- his upbringing, his business dealings, his penchant for lawsuits, and his inability to lose or let go of a grudge -- is examined, using golf as a lens. And these, in turn, may possibly explain his foreign policy, attitude toward Puerto Rico, even his Twitter usage. The content of this thorough book is equally humorous and disturbing.
