A large crowd at Georgia Southern University's Hanner Fieldhouse Wednesday night got a few laughs out of two polar political opposites who just happen to be married. James Carville and Mary Matalin, two renowned political commentators, both visited GSU to share insight on today's economy, political issues and how they maintain their marriage. Carville is a devout Democrat, a political consultant who ran Bill Clinton's 1992 campaign and includes Pennsylvania Sen. Robert Casey and former Georgia governor Zell Miller in his list of clients.
