The first Democratic primary debate is on June 26 -- but not every candidate has met the thresholds for support and donations to qualify for the party's debates.

Here is a rundown of how candidates can qualify for the first two debates, and who has qualified so far:

How candidates qualify for the debates

In an effort to give most candidates the chance to appear on the debate stage, the Democratic National Committee has scheduled 12 debates in total, with the first one set for June. The debates will be split up into two consecutive nights, with candidates randomly chosen to appear on each date.

To qualify for the first two debates, candidates have to fulfill one of two criteria: either get 65,000 donors to their campaigns, with at least 200 donors in 20 different states, or obtain at least 1 percent in three polls recognized as legitimate by the committee. If more than 20 candidates qualify for the debate, the DNC has said it will choose participants with "a methodology that gives primacy to candidates meeting both thresholds, followed by the highest polling average, followed by the most unique donors."

Joe Biden: The former vice president had qualified for the debates before he even entered the race on Thursday, as he has been steadily leading the polls. His campaign said that he reached the fundraising threshold in the first 12 hours of the campaign.
