The New York Times puts together the ways Russian hackers used Facebook to harness the rage that helped elect Donald Trump in 2016.
Note that in many cases the Russian media moles merely improved or simply broadcast things real American voters already were circulating. Trump himself had the same knack. Note that a photo of a Hillary Clinton campaign rally featuring happy faces of minority supporters is used as an illustration of a tactic of sowing division. Think kneeling football players. Who needs Russians?
