Six Democrats made the seventh presidential primary debate. The candidates took the stage in Iowa, less than three weeks before the first-in-the-nation caucuses there.
- Joe Biden said it will be "irrelevant" to the campaign if President Trump is acquitted in the upcoming impeachment trial.
- Can a woman win? The candidates agreed that the answer is yes. Bernie Sanders denied Elizabeth Warren's accusation that he told her they can't in 2018.
- As the candidates debated trade, Sanders stood out as the only opponent of USMCA, the replacement for NAFTA.
- Matters of war and peace dominated the first half of the debate.
NPR reporters are providing background and analysis of the candidates' remarks in real-time.
