With the deadline to qualify for next month’s third round of Democratic presidential debates closing in, the Democratic National Committee is facing an angry chorus of criticism from the candidates not likely to make the cut. At issue is the DNC’s criteria for the contenders to take part in the prime-time showdown, including contributions from 130,000 individual donors and reaching at least 2 percent in four qualifying polls.Ten candidates have already qualified to make the stage for the third debate – as well as October’s fourth round. They are former Vice President Joe Biden; Sen. Cory Booker of New Jersey; South Bend, Ind., Mayor Pete Buttigieg; former Housing and Urban Development Secretary Julian Castro; Sens. Kamala Harris of California and Amy Klobuchar of Minnesota; former Rep. Beto O’Rourke of Texas; Sens. Bernie Sanders of Vermont and Elizabeth Warren of Massachusetts; and tech entrepreneur Andrew Yang.
