In the second of three debates between presidential candidates, Senators John McCain and Barack Obama answered questions submitted by a group of uncommitted voters identified by the Gallup Organization and via electronic mail. Questions focused on the economy, the crisis in the financial markets, U.S. troop deployments overseas, and other foreign policy issues. During this town hall format debate, the candidates were seated on stools and free to move around the stage. Tom Brokaw moderated the event held at Belmont University in Nashville, Tennessee. The debate was shown in a full-screen format provided by the television network pool.
