Debate night is coming. Tony Schwartz, the man who channeled Donald Trump to write “The Art of the Deal” and has lived to regret it, explains why he is turning his intimate knowledge of how Mr. Trump thinks and behaves into advice for how Hillary Clinton should conduct herself in Monday night’s highly anticipated presidential debate. We also talk about what to expect on Monday with Frank Bruni, a New York Times opinion columnist, and Amy Chozick, a New York Times reporter who has covered Mrs. Clinton for the last two years.
