This week, Sam Tanenhaus discusses the life of William F. Buckley Jr., the man who set the blueprint for the modern conservative movement, which has reached a new iteration in Donald Trump. Then, speaking of consequential figures, we consider a man who left an enormous impact on Hollywood: Desi Arnaz. Todd S. Purdum tells us all about Arnaz’s groundbreaking life and career. And finally, a special treat: Cazzie David joins us from Los Angeles to share her answers to 50 of life’s most pressing questions in this week’s Perfect Ending.
