How was the stage decided?
The DNC announced in January there would be no donor threshold for the Nevada debate, which opened the door for Bloomberg, who hasn't sought fundraising, to qualify for his first contest.
In order to qualify for Wednesday's debate, a candidate either needed 10% in four qualifying national, Nevada or South Carolina polls, or 12% in two qualifying polls from Nevada or South Carolina. A candidate was also able to qualify if they received a single delegate from either the Iowa caucuses or the New Hampshire primary. The donor threshold, which previously required candidates to receives donations from a certain number of people, has been dropped.
What happened at the last debate?
The eighth Democratic presidential debate, which was ahead of the New Hampshire primary, turned into a pile-on against Buttigieg and Sanders, who both outpaced the field in Iowa. Klobuchar was the most direct in her challenges. But Warren dinged Buttigieg over his answer on marijuana arrests in South Bend. Biden sharply criticized Sanders' 1990s votes on gun control. Steyer played his most central role in any debate yet, and entrepreneur Andrew Yang, who has since dropped out, took a shot at Buttigieg.
