What to expect at the 7th Democratic debate

The top 2020 Democratic candidates are about to face off during the crucial last debate prior to the Iowa caucuses.

Tuesday's debate in Des Moines, Iowa, will consist of the smallest group of candidates so far, as six Democrats qualified: former Vice President Joe Biden, Sens. Bernie Sanders (I-Vt.), Elizabeth Warren (D-Mass.), and Amy Klobuchar (D-Minn.), former South Bend, Indiana, Mayor Pete Buttigieg, and billionaire Tom Steyer. Entrepreneur Andrew Yang didn't make the cut, meaning the debate stage will lack any people of color, NBC News notes.

Pundits are keeping a close eye on Sanders and Warren, whose feud escalated Monday after a report that Sanders told Warren during a private 2018 meeting that a woman couldn't win the presidency in 2020. Sanders denied it, and his campaign manager called it a "lie," but Warren subsequently made the claim on the record. How will the candidates address this dispute?

"Given her recent struggle for momentum and Sanders' rise, this is a fight that Warren wants and needs," The Associated Press observes, suggesting this may be Sanders' "turn for the front-runner treatment." Indeed, Politico writes that the debate "could be a doozy," as Democrats "reluctance to brawl is now a vestige of the past."

Expect plenty of foreign policy questions amid tensions with Iran, as well. During this discussion, Biden's vote for the Iraq war "could receive more scrutiny," especially from Sanders, The New York Times writes.

The debate, CNN notes, is also particularly important for the senators on the stage, who could soon be forced off the campaign trail for President Trump's impeachment trial. That's especially true of Klobuchar, who CNN notes "needs a breakout night." The debate is also Buttigieg's "last chance to stop" slipping poll numbers in Iowa before the caucuses, CNN points out.

The debate is set to air at 9:00 p.m. Eastern on CNN. The eighth Democratic debate is scheduled for Feb. 7, several days after the Iowa caucuses on Feb. 3.
