Why Are There No Black Women in the Senate?

Congresswoman Donna Edwards ran to be the only Black woman in the U.S. Senate during Maryland's 2016 primary. She's a strong progressive and a real champion of social justice who ran to represent the 4th Blackest state in the country. Why then, did the Democratic Party - the party of inclusion and diversity - fail to support her? How much longer until we have a truly reflective democracy?
