The right-wing radio host Rush Limbaugh has died at the age of 70. His daily program was filled with racist conspiracy theories and disinformation, and it helped transform the Republican Party, leading to the rise of Donald Trump. Over the years, Limbaugh often targeted Barack Obama, people with AIDS, immigrants, environmentalists and feminists, whom he dubbed “feminazis.” He also downplayed the severity of COVID-19, climate change and smoking. He died of lung cancer.
