Query: Disconcerting

Ronald Reagan is NOT a hard man to understand. He's a simple man (of great integrity) from a simple place and a simple time who became a great leader of a great country. Why do we have to plow through over 800 pages and the lives of fictionalized characters to understand this? In a biography???? So much of Ronald Reagan's time as Governor of California and President of the United States has been ignored in this book. In 1985/86 when Edmund Morris became confused about his subject, he should have begged off the project immediately and given someone else the chance of a lifetime. It's just disappointing that Mr. Morris, who was given this opportunity, has squandered it. David McCullough, where are you?
