The DNC's outline for its September debate — the third of at least a dozen promised matchups during the 2020 nominating contest — decrees that candidates can participate only by reaching 2% in four approved polls released between June 28 and Aug. 28 while also collecting contributions from a minimum of 130,000 unique donors before Aug. 28. That donor list must include a minimum of 400 individuals in at least 20 states. The qualifications would remain the same for an October debate, though the party hasn't set the deadline for measuring fundraising and polling.
