Trump speech signals shift to coded racist language

During the primaries, Donald Trump threw red-meat rhetoric to supporters, pledging to build a wall on the Mexico border and to ban Muslim immigrants. Now that he’s the GOP presidential nominee, some observers say he’s turning to code words to incite racial animosity and fear among America’s white voters. Ian Haney Lopez is author of “Dog Whistle Politics: How Coded Racial Appeals Have Reinvented Racism and Wrecked the Middle Class.” He says Trump singled out refugee families with unknown backgrounds by saying they threaten to transform the nation. The speech, Lopez says, essentially declared that “the barbarians are at the gate.”
