FILE - In this Oct. 15, 1992 file photo, Moderator Carole Simpson, background center, presides over the Presidential debate between, from left, Democratic presidential candidate Bill Clinton, Independent candidate Ross Perot, center, and Republican candidate, President George H.W. Bush, at the University of Richmond, Va. The every-four-years ritual of a national "town hall" style debate began as a nerve-racking experiment in live television. Simpson was so nervous about turning over the microphone to regular folks and their questions that she spent days mapping out the presidential candidates and their issues on "a zillion 3-by-5 cards," in case she had to take over the questioning herself.
