“Saturday Night Live” went all in against Donald Trump with a mock campaign ad depicting his supporters as Nazis, KKK members and white supremacists. The ad started with “real Americans” explaining their support for the Republican front-runner, until the camera panned out to reveal them partaking in such activities as wearing a swastika armband, ironing a KKK hood, and burning a cross. It ended with the title, “Racists for Trump.” The clip aired hours after Trump instructed Florida rally-goers to raise their right hands and recite a pledge to vote for him, creating a jarring visual many likened to Nazi imagery and prompting the term “Heil Trump” to trend on Twitter.
