How do I watch the Democratic debate?

The 2016 Democratic presidential candidates will take the debate stage for the first time Tuesday night, Oct. 13, in Las Vegas, Nevada.

• Watch CBSN coverage during and after the debate

Hosted by CNN and Facebook and sanctioned by the Democratic National Committee (DNC), the debate will be held at the Wynn Las Vegas, and Anderson Cooper will moderate.

Debate host CNN released the candidates' placement on the stage, which is based on their poll positions. Hillary Clinton will stand at the center of the stage, flanked by Bernie Sanders on her right, and Martin O'Malley to her left, and Jim Webb and Lincoln Chafee, who polled fourth and fifth, respectively, on each end.

Vice President Biden is not likely to participate, but should he have a last-minute change of heart and mind, CNN would welcome him on stage. In fact, they even have a podium designated for him.

• Where to watch: on TV: CNN; on computer: CNNgo
• Time: 8:30pm ET to 11pm ET
• What: Democratic presidential debate

One Democrat who will not be on stage is Larry Lessig, a Harvard law professor who only announced his campaign last month, after raising $1 million for his single-purpose campaign: campaign finance reform. He did not meet the 1 percent support threshold set by CNN.

And one of the DNC's top officials seems likely not to attend. Rep. Tulsi Gabbard, D-Hawaii, a top official in the Democratic party, was originally invited, but she told the New York Times that she was disinvited from the Democrats' first 2016 presidential debate after publicly suggesting there should be more debates.

CNN is also going to live-stream the debate in 3-D virtual reality, so that viewers who have the appropriate Samsung virtual reality headset and smartphone can watch as if they are in the live audience. What this means, according to a news release, is that users "are able to hold a gaze on a particular candidate" and "catch off-screen interactions."
