a 2020 two-part television documentary film about the political divide between the United States Democratic and Republican Party in the early 21st century. Produced by the investigative journalism program Frontline on PBS, it charts how the two major political parties became increasingly adversarial to each other due to factors of race, media, and misinformation, from the 2008 presidential election to the presidency of Donald Trump. The film was directed by Michael Kirk and written by Kirk and Mike Wiser, and was first aired on PBS in two parts on January 13 and 14, 2020.
