The fourth round of Democratic debates will be held on Oct. 15 in Westerville, Ohio, with 12 candidates onstage, making it the biggest single-night debate to date.
How it works: This debate had the same requirements as September's. Qualifying candidates must have reached 2% in 4 DNC-approved polls and drawn 130,000 unique donors — including 400 donors in 20 different states. Oct. 1 was the final day to make the cut.
Why it matters: The Democrats' massive 2020 field has put pressure on the DNC to focus its primary on those who can really challenge President Trump.
Which candidates will be on stage:
- Sen. Amy Klobuchar
- Sen. Cory Booker
- Mayor Pete Buttigieg
- Sen. Bernie Sanders
- Former Vice President Joe Biden
- Sen. Elizabeth Warren
- Sen. Kamala Harris
- Entrepreneur Andrew Yang
- Former Rep. Beto O'Rourke
- Former HUD Secretary Julián Castro
- Billionaire and activist Tom Steyer
- Rep. Tulsi Gabbard
Candidates that had at least 130,000 donors but did not meet the polling threshold:
Candidates who did not meet any qualifications for Ohio:
- Mayor Wayne Messam
- Former Rep. Joe Sestak
- Former Rep. John Delaney
- Rep. Tim Ryan
- Sen. Michael Bennet
- Gov. Steve Bullock
