On Tuesdays, the station will air “The Politics of Culture,” which examines where politics and culture meet. “Left, Right & Center,” a 13-week series on politics airing on Wednesdays, features revolving hosts, including writer Robert Scheer; Genevieve Wood, a moderator of TV discussions; Matthew Miller, economics editor of the New Republic; and political activist Arianna Huffington. “Bookworm” moves to Thursdays. “The Treatment,” a show about popular culture hosted by NPR entertainment critic Elvis Mitchell, will air on Fridays.
