The 7 candidates who qualified for the December debate

Seven candidates have cemented their spot on the next debate stage, a significant drop from the 10 who appeared last month.

Former tech entrepreneur Andrew Yang was the last addition to the sixth 2020 Democratic presidential debate, which will take place December 19 in Los Angeles. Senator Kamala Harris was qualified but dropped out of the race last week.

According to a CBS News analysis, the following seven Democratic candidates qualified:

Former Vice President Joe Biden

Mayor Pete Buttigieg

Senator Amy Klobuchar

Tom Steyer

Senator Bernie Sanders

Senator Elizabeth Warren

Andrew Yang

The bar to qualify was raised once again. Candidates needed to prove that they have at least 200,000 unique donors, including at least 800 in 20 different states, U.S. territories or the District of Columbia. That's an increase from 165,000 last month. They also had to reach either 4% in at least four national or early-state polls or reach 6% in two early-state polls. That's an increase from 3% and 5%, respectively.

The debate will be hosted by PBS NewsHour and Politico.

Ten candidates took the stage for November's debate in Atlanta. Previous debates have taken place in Detroit, Houston, Miami and Westerville, Ohio.
