Obviously it wasn't swept under the rug, I've heard about this for ages. And what would be the point of going after a looney? It's not like it makes any difference in the scope of things.
As opposed to Trump hiring an advocate for White Supremacists (rebranded alt right) to run his campaign, to Trump running his scam "University", which even his employees agree was a scam, to Trump apparently taking money from a charity to pay his legal bills, to Trump openly courting racists to join his base.
So, let's look at some facts:
Exclusive: Trump supporters more likely to view blacks negatively
Nearly half of Trump's supporters described African Americans as more "violent" than whites. The same proportion described African Americans as more "criminal" than whites, while 40 percent described them as more "lazy" than whites.
...
32 percent of Trump supporters placed whites closer to the top level of "intelligence" than they did blacks
So, according to the facts, nearly 1/2 of Trump's supporters are racist. (Hillary nailed it!) And how many lied to the pollster because they were too embarrassed to admit that they were racists?
Fact: According to this poll, if I'm arguing with two Trump supporters, the odds are good that at least one of them is a racist.
I would call that "Deplorable". I would call those people who are racists, nearly half of all Trump supporters, "Deplorable".
