The Nation’s editor and publisher Katrina vanden Heuvel appeared on Voices from the Frontlines Radio to discuss what it would take to build a progressive grassroots movement and bring about actual change in America.

Vanden Heuvel lists some of the many challenges a successful movement would have to overcome, from building political support to bridging the partisan gap. Yet she also cites causes for optimism, such as the Occupy movement, which she calls “the most serious and sustained national conversation we’ve had in too long,” and the significant impact Occupy has already had on President Obama and our political discourse.
