What Time, Channel Is Tonight's Democratic Debate for Sunday, Jan. 17?

Democrats Hillary Clinton, Bernie Sanders and Martin O’Malley will hold the last Democratic debate before the Iowa caucuses Sunday at 9 p.m. in Charleston, South Carolina, in a meeting that could prove fiery.

The Sunday Democratic debate will air live on local NBC stations.

Live streaming video of the debate will also be available on NBCNews.com, the NBC News YouTube channel and via NBC’s various apps for different types of devices.

Democratic presidential polls show Clinton barely ahead in Iowa and Sanders atop the polls in New Hampshire.

The Iowa caucuses will be held Feb. 1 followed by the New Hampshire primary Feb. 9. South Carolina holds its Democratic primary Feb. 27.

While the races are tight in the first two voting states, an NBC New/Wall Street Journal poll released ahead of the debate showed Clinton leading Sanders nationally by 25 points.

Clinton is the first choice of 59 percent of Democratic primary voters, while Sanders gets the support of 34 percent. Martin O’Malley gets 2 percent, according to the poll.

That contrasts sharply with a New York Times/CBS News poll that released Jan. 12. It showed Clinton with a 7-point lead.
