For those of you who wonder how the Republican Party could have chosen a leader with a racist past (whose closest advisor is a white supremacist and attorney general a racist), these charts might help you understand. The Republican Party is still basically a party made up of white people (86%). And they have done very little outreach to include non-whites in their party.
On the other hand, the Democratic Party is much more diverse -- with whites making up 57% and non-whites making up 43% of party membership. And their diversity grows with each presidential election year.
These charts were made from information provided in Pew Research Center polls done from 1992 through 2016.
