ABC News Democratic Debate 2015: Preview, Viewing Info and Guide to Moderators

The Democratic presidential candidates will take the stage again Saturday night for the third Democratic debate, to be hosted by ABC News. The debate will take place at Saint Anselm College in Manchester, New Hampshire.

The debate, which will air at 8 p.m. Eastern, will be co-moderated by David Muir, anchor of ABC's World News Tonight and ABC's chief global affairs correspondent Martha Raddatz.

Three candidates will appear in Saturday's debate: former Secretary of State Hillary Clinton, Vermont Sen. Bernie Sanders and Maryland Gov. Martin O'Malley.

Saturday's debate will be the last Democratic primary debate of 2015, and the only Democratic debate to be hosted in New Hampshire, according to ABC. 

Local ABC affiliate WMUR- was scheduled to co-anchor the debate, with WMUR's Josh McElveen moderating alongside Muir and Raddatz, but on Friday the station announced that, due to "ongoing labor negotiations" between WMUR employees and the network's parent company, Hearst Television, the Democratic National Committee had decided to "no longer include WMUR in the debate." 

George Stephanopoulos is scheduled to take the lead on coverage of the debate for ABC. Viewers can tune in to ABC on Saturday night to watch the debate or livestream it through the ABC News website or mobile app.
