Michael Barbaro hands the host chair to his editor, Carolyn Ryan, who runs campaign coverage for The New York Times, to discuss the tape of Donald J. Trump talking unguardedly about women and his behavior toward them and why it has blown open a discourse on gender, politics and culture. She speaks with Maggie Haberman, who has covered both Hillary Clinton and Mr. Trump, and Maureen Dowd, The Times’s Pulitzer Prize-winning columnist and a historian of the Clintons.
