As the presidential election approaches, Talk of the Nation asks guests to make the case for McCain or Obama on the basis of foreign and domestic policy credentials. Sarah Sewall, senior foreign policy adviser for the Obama campaign, explains why she thinks Obama is the right choice in 2008.
Sewall was formerly the deputy assistant secretary of Defense for Peacekeeping and Humanitarian Assistance under Bill Clinton. She is faculty director of the Carr Center for Human Rights Policy at Harvard University.
