FILE - In this Oct. 15, 1992, file photo President George H.W. Bush looks at his watch during the 1992 presidential campaign debate with other candidates, Independent Ross Perot, top, and Democrat Bill Clinton, not shown, at the University of Richmond, Va. Finally, the fall season delivers the matchup Americans have been waiting for, President Barack Obama goes one-on-one with Republican Mitt Romney in three prime-time debates. With the race a dead heat, the debates take on an oversized role in the few weeks between now and Election Day. One small mistake or impression _ a glance at a watch, repetitive sighing _ could roil the campaign for days and linger in voters' mind. This is especially true for two polished candidates who will have the soundbites and rhetoric down cool.  (AP Photo/Ron Edmonds, File)
