The Black Group exists simply due the fact that they represent nearly 50% of the democrat party. Let that sink in for a moment. The majority of the 13-14% of American Blacks identify as democrats. If you surmise that the democrats represent 35% of the US population, and that 13% of the US population is Black one can quickly understand why the DNC is being hijackedy by the Revoluntary Leftists and a under that revoluntary subgroup a progressive Christian-Communist church organization being preached too.
To recap, the US Population is about 50% white, 13% black, and 5% Asian, 15-20% Anglo/Lationo Hispanics and then the other groups. The white population is evenly divided at about 35-35-30 Dem/Independents/Rep. The DNC's 13% of the total population being black means that they donot represent ony 25% of dem party, but because few blacks are independents, they actually approach 40-43% of the total DNC lever pulling constituency.
But what was the percentage of the United States Citizens who actually voted in that election?
And how does that percentage change your point.
There were higher percentages of Black and other races that voted for Trump than in other elections, mostly because of their disgust with the whole system ignoring their voice.
