It's a fast read; I just finished reading it on a flight to New York. It's not a tittle-tattle like Fire and Fury but instead a highly articulate and readable indictment of everything wrong with Donald Trump.
The book, however, was not written by a fire-breathing liberal. Frum is a conservative Republican and served in George W. Bush's administration as a speechwriter, and his fine skill with concise, crisp language is found on every page.
He doesn't attack Trump on ideology, however. He takes the President to task for his corruption, incompetence, self-dealing, arrogance, cruelty, and greed.
The book, surprisingly, has an optimistic ending. Because Trump is such a wretched President and has corrupted the American political system, he has inspired a new sense of civic engagement and responsibility. Americans throughout the country are now becoming more involved in politics and running for office so that our nation will be come back stronger and better once Trump leaves office.
