Query: Beware!

I ventured into this book knowing full well that Hertzberg is what we Conservatives call a bleeding-heart Liberal. But, as a former executive secretary of the Conservative Party, I enjoy a good political debate, and I was aware of Hertzberg's strong reputation as a writer. The book began with some innocuous comments on music and Woodstock. Then came a long essay on the strengths and weaknesses of Jimmy Carter. Surprise! I found I agreed with much of what Hertzberg had to say. But then came a strongly biased diatribe on my main man Ronald Reagan. This mean spirited attack on one of the greatest Presidents who ever served was more than I could stomach. I oppose book burning, but this tome is a strong counter-argument. No matter how bad I find a book, I usually manage to finish it. This is one of only a handful of exceptions.
