That 9% includes those who lean Republican but are not necessary going to support the Republicans. What’s more, the reference you listed is from 2015. Things have changed a bit since then. You may have noticed a few protests nationwide since then.

Also, I strongly encourage you to Google images of Trump’s rallies, and see how many POC are there. Sure, you’ll find a few, and quite often, those POC (especially Blacks) are placed in high-visibility spots…and if you watch a Fox broadcast of a Trump rally, you’ll see the camera swing to the token Black persons time and time again.

Yes, it’s wrong to say all of any particular demographic does this or says that…but that doesn’t make a particular political party any less supportive of racists and racism. Again, check the pictures. Each one is worth a thousand words.
