A conversation about what it will take to preserve our freedom, our democracy, and our future for the next 250 years—and what the last 250 have taught us about the work still unfinished. As the nation marks a quarter-millennium since its founding, this panel brings together historians, poets, journalists and policy experts to explore what “a more perfect union” has meant, who has been included in that promise, and what it demands of us now. Featuring historian William Hogeland, poet Martín Espada, editor and author Regina Mahone, and writer and podcaster Dave Zirin. Moderated by John Nichols, Executive Editor of The Nation.
