For much of 2024, Donald Trump has used demagoguery against migrants to campaign for the White House. In numerous recent speeches and media appearances, he has continued to inveigh about an alleged “invasion” coming across America’s southern border. He has falsely claimed that hordes of violent and “insane” foreigners have been taking over “hundreds” of cities and raping and killing “thousands of Americans.” His repeated vows to deport millions of undocumented immigrants draw roars of approval at his rallies. Inflaming Americans’ fears about immigration and border security was a hallmark of Trump’s presidency and previous campaigns—and his extreme rhetoric, as I’ve previously reported, has marked spasms of violence, including a horrific mass shooting in 2019 in El Paso, Texas.
