Open Image ModalMembers of the media are given a preview of the debate hall at the Wynn Hotel in Las Vegas, Nevada on October 13, 2015, hours before the first Democratic Presidential Debate. After ignoring her chief rival for months, White House heavyweight contender Hillary Clinton steps into the ring Tuesday to confront independent Senator Bernie Sanders in their first Democratic debate of the 2016 primary cycle. Clinton will take center stage in Las Vegas joined by Sanders and three other hopefuls, and while there is unlikely to be a dramatic clash of personalities as seen in the first two Republican debates, the spotlight is likely to be on the top two candidates. The other three challengers -- former Maryland governor Martin O'Malley, ex-senator Jim Webb and former Rhode Island governor Lincoln Chafee -- will try to generate breakout moments to show they are electable alternatives to Clinton.
