Which Candidates Qualified For The September Debates?

Twenty candidates participated in the Democratic Debates.
Now, it looks like that number will shrink significantly.
The Democratic primary debates for September have significantly more strict qualifying thresholds.
Candidates must reach 2% in at least four separate polls approved by the Democratic National Committee.
They must also receive at least 130,000 individual donations.
That must also include 400 donors in at least 20 states or US territories.
