Trump, who is really as dumb as a stump, is an idiot savant when it comes to marketing and understanding his base. I don't think he really gives it any real thought, it just comes to him naturally. Unfortunately. He probably doesn't even think he's a racist but whatever it takes for him to get and stay and power and make lots of money he will do it. This is why he was a democrat and realized there was way more money in bashing Obama than running for President. George Wallace was an active racist who knew what he was doing. I don't think Trump cares. Like an idiot savant that can crunch numbers without trying, he knows how to rent space in our minds
