Key takeaways from Democratic presidential debate in Iowa
Six Democratic presidential candidates took the debate stage in Des Moines, Iowa, in a final showdown before primary voting begins.
There was a lot of pre-debate chatter about a coming fight between Senators Bernie Sanders and Elizabeth Warren over Warren's assertion that Sanders told her in 2018 that a woman couldn't be elected president.
Warren made an energetic case for a female nominee that raised gender as a core issue in the Democrats' sprint to the Iowa caucuses.
Sanders firmly denied Warren's accusation and said it was “incomprehensible” to believe he would suggest a woman couldn't become the president.
The candidates also sparred over Iraq, war and foreign policy.
