No Candidates of Color in 7th Democratic Debate VOA News WASHINGTON - The head of the Democratic Party, Tom Perez, insists the party is committed to diversity even though Tuesdaynight'spresidential debate in Iowa will be the first all-white debate of the 2020 campaign. Since the last Democratic showdown in December,Senator Cory Booker of New Jersey, an African American, and Latino candidate Julian Castro -- the former mayor of San Antonio and federal housing secretary --dropped out of the race for the Democratic nomination to challenge U.S. President Donald Trump in November.. Among the remaining candidates, Asian-American entrepreneur Andrew Yang; Congresswoman Tulsi Gabbard of Hawaii, a Samoan American; and the black former governor of Massachusetts, Deval Patrick, did not qualify for Tuesday's face-off only weeks before the Iowa Caucuses. All three failed to meet the criteria set up by the party. They include polling at least 5% in four polls and raising funds from at least 225,000 individual donors. .
