Your question has nothing to do with it. Most of us here aren't particularly racist, so of course we'd rather be rich and black. That article points out that, amongst Trump supporters, they tend to feel otherwise.
You can survey us all you want, we do not represent the electorate. You may have a reading comprehension issue, as the whole premise of that article is that Trump rode along the back of the idea that the best black person is still inferior to the worst white person. Our opinions are immaterial in this, as none of us voted for Trump.
