Query: Poorly written and edited, plus rife with errors

As noted, this book is filled with numerous typos and flat-out grammar errors (the author might want to review the difference between "affect" and "effect").Further, there are a significant number of factual errors in the book. For example, I'm sure Eugene McCarthy would be disappointed to learn that he is described as one of the architects of the 50's Red Scare.Finally, perhaps most seriously, much of the text of at least one chapter is suspiciously similar to a major write-up on a web site (and I confirmed that the author of the web site is not the author of this book).
