Donald Trump (All General Trump Conversations Here)
If Trump is caught saying the N-word on tape, Americans will care (and there's little doubt he said it now. One of his spin doctors, Katrina Pierson, is on Omarosa's latest tape saying he did and discussing how to "spin" it). Of course, his rabid anti-*immigrant white nationalist base won't care, but they don't make up more than twenty of the forty percent who support him. The other twenty won't like it and he only needs to lose a small percentage of those to become unelectable.
*Before someone says they're only anti-
illegal immigrant, I refer you to Laura Ingraham of Fox News who has let the cat out of the bag on that one in a recent racist video where she talked about fighting the "demographic" changes caused by illegal
and legal immigration. "Demographic" as in too many non-whites who are now threatening to make whites a minority. This echoes Nazi and white nationalist propaganda, which is why David Duke of KKK fame and other racists responded so positively calling it:
"One of the most important (truthful) monologues in the history of [mainstream media] MSM"."

So, a lot of racist sentiment in the US, both overt and covert, but the vast majority of Americans are not going to go with the overt stuff (as
Maw pointed out), so despite the efforts of Trump's base and Trump himself in taking it mainstream, it will never get there. Apart from anything else, it's bad for business.
