Earlier this year, prior to the first Democratic debates, the DNC announced more stringent qualifying rules for the fall debates in September and October. Details for the October debate have not yet been announced.

In order to qualify for the September debate, candidates must cross both the polling and grassroots funding thresholds. Candidates must receive 2% or more support in at least four national polls, or polls conducted in the early-voting states of Iowa, New Hampshire, South Carolina and/or Nevada and publicly released between June 28 and August 28.

Any candidates’ four qualifying polls must be sponsored by one or more of the following organizations approved by the DNC: The Associated Press, ABC News, CBS News, CNN, the Des Moines Register, Fox News, Monmouth University, NBC News, The New York Times, National Public Radio, Quinnipiac University, University of New Hampshire, The Wall Street Journal, USA Today, the Washington Post, and Winthrop University. They also must be conducted by different organizations or -- if by the same organization -- must be in different geographical areas.

Candidates must also receive donations from at least 130,000 unique donors over the course of the election cycle, with a minimum of 400 unique donors per state in at least 20 states. Qualifying donations must be received by 11:59 p.m. on Aug. 28 for the September debate.
