Why Blacks are unhappy with Barack Obama? Will they not vote for Harris this time?

In response to the challenge tossed his way by Barack Obama to vote for Kamala Harris, the Black Men for Trump advisory board has fired back at him today saying that his pitch was "deeply insulting" and accused him of promoting identity politics. Obama said that American policies required every black man to vote for Kamala Harris. According to them, Black Americans should evaluate candidates by their track records and not by just their skin color, as per report.
