Seven candidates qualified for the sixth Democratic 2020 presidential debate, scheduled for Dec. 19 at Loyola Marymount University in Los Angeles, California.

Driving the news: All qualifying candidates have said on Twitter they won't attend the debate unless the host, Loyola Marymount University, reaches a deal with its workers in an ongoing labor dispute.

How it works: December's polling requirements included at least 4% of support in at least four DNC-approved national or early-state polls.

  • Candidates could also qualify by hitting 6% in two approved early-state polls.
  • Contenders need at least 200,000 unique donors, with a minimum of 800 donors in 20 states.
  • The event will be moderated by Politico's Tim Alberta and PBS' Judy Woodruff, Amna Nawaz and Yamiche Alcindor.

Candidates who will be on stage:

  1. Former Vice President Joe Biden
  2. Sen. Elizabeth Warren
  3. Sen. Bernie Sanders
  4. Mayor Pete Buttigieg
  5. Sen. Amy Klobuchar
  6. Billionaire Tom Steyer
  7. Entrepreneur Andrew Yang

Candidates who met donor qualifications, but not polling requirements:

  1. Rep. Tulsi Gabbard, who said on Monday that she will not attend the debate whether she qualifies in the polls or not. She said she plans to travel to South Carolina and New Hampshire instead.
  2. Sen. Cory Booker, who made it clear in September that his campaign needs more funding to stay in the game.
  3. Former HUD Secretary Julián Castro, who failed to qualify for the November debate stage weeks after threatening to drop out over waning fundraising.

Candidates that did not meet any qualifications:

Author Marianne Williamson, Former Gov. Deval Patrick, Former Rep. John Delaney, Former New York Mayor Michael Bloomberg and Sen. Michael Bennet.
