How to watch tonight's Democratic presidential debate

The debate, hosted by MSNBC and The Washington Post, will take place in the shadow of televised impeachment hearings in Washington. Hours before the debate's start time, officials, including the US ambassador to the European Union, publicly appeared before the House Intelligence Committee.

South Bend, Indiana, Mayor Pete Buttigieg enters debate night after emerging as the clear leader in the most recent CNN/Des Moines Register Iowa poll. Like Massachusetts Sen. Elizabeth Warren, who entered the October debate with momentum, Buttigieg could face more direct attacks from his opponents during Wednesday night's event given his increased standing in the race.

Since the last debate, three candidates have suspended their campaigns: former Texas Rep. Beto O'Rourke, Ohio Rep. Tim Ryan and Miramar, Florida, Mayor Wayne Messam. Former Massachusetts Gov. Deval Patrick also launched a late-entry presidential bid, and former New York City Mayor Michael Bloomberg is now considering getting into the race. These moves signal the Democratic primary race continues to be unsettled 75 days out from Iowa's first-in-the-nation caucuses.

The debate will air live at 9 p.m. ET on Wednesday from Tyler Perry Studios in Atlanta. It will run for two hours.

How was the stage decided?

The DNC has progressively raised the qualifying thresholds for the primary Democratic debates that began in June. In order to make the November stage, candidates had to reach 3% in at least four DNC-approved national or early state polls or at least 5% in two polls of the early-voting states: Iowa, New Hampshire, Nevada and South Carolina. Candidates also had to raise money from 165,000 separate donors, including a minimum of 600 donors each in at least 20 states or territories.

What happened at the last debate?

The party's fourth presidential debate, hosted by CNN and The New York Times, showcased the shifting dynamics of the Democratic primary. It was one of the first times Warren faced a barrage of critiques from her Democratic competitors. Biden, the other front-runner, stayed out of the fray for much of the event -- until a late clash with Sanders that featured the same one-on-one, progressive-against-moderate battle that has defined the 2016 Democratic contest. Moderate candidates like Buttigieg and Klobuchar pressed their progressive foes in direct and sometimes personal terms.
