What time is the January Democratic debate, and what’s at stake for candidates onstage?

The Democratic presidential field is set to have its smallest and potentially most influential debate yet. It could also become among the most contentious if candidates bring their campaigns’ offstage issues onstage.

On Tuesday at 6 p.m. PST, six candidates are slated to gather at Drake University in Des Moines to slug it out less than three weeks before the first-in-the-nation caucuses in Iowa.
