His work focuses on strategic communication practices of political associations in America, with a particular interest in Internet-related strategies. David “is the author of The MoveOn Effect: The Unexpected Transformation of American Political Advocacy,” which highlights the disruptive role that the Internet has played in the advocacy group system. It provides the first detailed analysis of the new generation of “netroots” organizations — groups like MoveOn.org and DailyKos.com — and examines how these new organizations differ from the older nonprofit organizations. Prior to entering academia, David was an environmental organizer with the Sierra Club. Follow him at @davekarpf.
