In a NYT editorial, demographics expert Thomas Edsall took a more scientific approach as to why Trump uses highly inflammatory rhetoric when speaking about minorities.
Through gut (or gutter) instinct, Trump has adopted a political strategy designed to exploit anger at and resentment toward immigrants as well as racial and ethnic minorities. This is the linchpin of his approach to the 2020 election.
He also notes that his colleagues, David Leonhardt and Ian Prasad Philbrick, once wrote: … “Trump himself has claimed that he is ‘the least racist person.’ But here’s the truth: Donald Trump is a racist. He talks about and treats people differently based on their race. He has done so for years, and he is still doing so.”
