During this holiday season, hear some recent favorites:

New York City's mayor-elect Zohran Mamdani defines himself as a democratic socialist, yet his critics have seized on his leftist identity to paint him as an extremist. Carlo Invernizzi-Accetti, professor of political science and executive director of the Moynihan Center at The City College of New York, and author of 20 Years of Rage: How Resentment Took the Place of Politics (Mondadori, 2024), explains the core principles of the various strains of thought on the left to paint a clearer picture of what Mamdani believes in and how he'll govern as mayor.
Joyce Vance, a legal analyst for MSNBC and former U.S. Attorney for the Northern District of Alabama, University of Alabama School of Law professor, and author of the Civil Discourse substack, and of the new book, Giving Up Is Unforgivable: A Manual for Keeping a Democracy (Dutton, 2025), talks about the rule of law and offers legal and historical context for the current moment in American history as she calls for citizens to uphold the Constitution.
Jared Fox, education consultant, former NYC secondary science teacher and the author of Learning Environment: Inspirational Actions, Approaches, and Stories from the Science Classroom (Beacon Press, 2025), guides teachers in taking science education out of the classroom, drawing on his experience teaching science in Washington Heights.
Randi Weingarten, president of the American Federation of Teachers (AFT) and the author of Why Fascists Fear Teachers: Public Education and the Future of Democracy (Thesis, 2025), talks about her new book and explains why she says education protects democracy.
Peter Harnik, co-founder of the Rails-to-Trails Conservancy and the Center for City Park Excellence at the Trust for Public Land and executive producer of the documentary "From Rails to Trails", talks about his work spearheading the movement to convert abandoned railbeds into multi-use trails, 26,000 miles so far, and the new documentary about it, plus listener suggestions for the best places to bike outside the city.
