Key Things to remember, the democratic party was the party of racism all through out American history.
Republicans have always been more diverse, the democrats tactic to flip this has been to suppress blacks and hispanics and other minorities including illegals and make them look like the care about them, but if you look at what Clinton did in the 90's with NAFTA he destroyed black communities and low income hispanic communities.
Larry Bird, Margaret Sanger, George Soro's, Clintons have all been against blacks \ cumulatively for more then 100 years.
