Al Gore Goes Back to the Capitol

Former Vice President Al Gore is back on Capitol Hill today for the first time since he certified his own defeat in the presidential election of 2002.  As a Tennessee Senator and Vice President he had trouble getting a hearing on global warming. Today, testifying before a House committee, he spoke of the growing demand for action on climate change by politicians across the board as well as religious leaders and industry.  Tom Schaller is Associate Professor of Political Science at the University of Maryland.
