The Democratic National Committee has announced that 20 candidates have qualified for the party's first presidential debates later this month.

Montana Gov. Steve Bullock and U.S. Rep. Seth Moulton of Massachusetts were the only major candidates out of the two dozen Democratic hopefuls who failed to meet the polling or grassroots fundraising measures required to get a debate spot. Two lesser-known candidates, former Sen. Mike Gravel of Alaska and Miramar, Florida, Mayor Wayne Messam, also missed the cutoff, announced Thursday.

US Senator Michael Bennet of Colorado and New York Mayor Bill de Blasio, who recently had been on the bubble, both made the debate based on polling measures.

The campaign's opening debates, set for June 26-27 in Miami, will offer a prime opportunity for many White House hopefuls to reshape a race defined in recent weeks by former Vice President Joe Biden's domination of national and many early state polls despite recent losses. An NBC News drawing Friday will divide the large field between the first and second debate night. Party officials have promised to weight the drawing with the intention of ensuring that top tier and lagging candidates are spread roughly evenly over the two nights. Those assignments will determine the debate strategies for many campaigns. Candidates will have to decide whether to go after front-runners such as Biden, challenge others in the pack or stand out by remaining above the fray. They must also decide how much to focus on President Donald Trump. Some candidates have criticized the debate-qualifying rules that the party chairman, Tom Perez, set this year. The polling and fundraising thresholds will remain the same for the July debates over two nights in Detroit.
