Over the last half-century, the Republican Party has exploited social divisions—and racism in particular—to win power, and then has ruled primarily on behalf of the ultra-wealthy. Meanwhile, the Democratic Party has struggled to respond effectively and has even stooped to imitation. In this conversation, Ian Haney López lays out the history of dog-whistle politics and Donald Trump’s place within it. Then he suggests a clear way forward. His research—discussed in his most recent book, Merge Left: Fusing Race and Class, Winning Elections, and Saving America—demonstrates that dog whistle politics can be defeated. Drawing on these results, this lecture assesses the looming 2020 presidential election.
