I grew up in Louisiana and much of my views on American politics is colored (ahem) by the David Duke campaign when I was a boy. About half of the state voted for a Klansman for governor, in the 1980s. I remember my grandfather, who I (perhaps incorrectly) took to be somewhat conservative said “you would have to be crazy to vote for that man”. Of course he was himself an immigrant and had probably been on the receiving end of American style racism at some point.
In November 2017 the Atlantic published an article that is worth reposting for the Walker Percy quote. Walker Percy was a National Book award winner,a south Louisiana resident and a keen observer of humanity. His quote and the article:
“Don’t make the mistake of thinking David Duke is a unique phenomenon confined to Louisiana rednecks and yahoos. He’s not,” Percy said. “He’s not just appealing to the old Klan constituency, he’s appealing to the white middle class. And don’t think that he or somebody like him won’t appeal to the white middle class of Chicago or Queens.”
Trump’s supporters backed a time-honored American political tradition, disavowing racism while promising to enact a broad agenda of discrimination.
