The third and final Democratic debate of 2015 will air live from Manchester, New Hampshire on 19 December. Three candidates – Hillary Clinton, Bernie Sanders and Martin O'Malley – will go head-to-head in the debate hosted by ABC News, the New Hampshire Democratic Party and the Union Leader. Like the first two debates, the debate at Saint Anselm College will not include an undercard debate.

The debate, which is unlikely to see the viewership numbers that the 15 December Republican debate experienced, will still be crucial for all three contenders. The latest national poll by Monmouth University revealed Clinton continues to hold a substantial lead (59%) over Sanders (26%); O'Malley, meanwhile, is on 4%, which was still a bump from October when he held only 1% of support.

ABC News's David Muir and Martha Raddatz will moderate the third debate. Raddatz previously moderated the 2012 vice presidential debate, while Muir spent two election cycles on the campaign trail.

When and where

Similar to the second debate, which was held at Drake University in Des Moines, Iowa, the third one will be held at a location of special political significance. According to Politico, Saint Anselm College's Institute of Politics regularly hosts presidential candidates and is scheduled to host one of the Republican debates in February.

The debate will also be held in a state that is partial to Sanders, who is the senator of neighbouring Vermont. He also leads Clinton in an aggregate of recent state polling, Politico noted. The event will begin airing at 8pm EST/1am GMT. ABC News has not released information pertaining to the debate's formatting and does not plan to before the event.

How to watch

The debate will air live on ABC and stream online for free at ABC News. No cable subscription will be needed to watch it online. Viewers will also be able to stream the debate for free on ABC's mobile, Apple TV and Roku apps. Bustle noted that ABC News will made the debate available for streaming on the Xbox One.
