Welcome to "The Stakes," our serenade to politics and social justice. Coming up on the show today: Part 1: Jane Coaston and Belinda O'Donnell speak with Zimbabwean Pastor Evan Mawarire, who helped trigger his country's #ThisFlag protest movement with a YouTube video. Part 2: Jamil Smith talks with Jonathan Katz, a journalist who lived in Haiti during the current cholera epidemic, about why it took the UN so long to admit to its role in the outbreak. Part 3: Julie Zeilinger sits down with Caia Hagel, the editor-in-chief of Sofa -- a new digital trends magazine that tries to figure out just what it is that Gen-Z is thinking. Part 4: Our poet-in-residence Marcus Ellsworth gives us his poetic take on the Supreme Court’s empty chair.
