Disinformation has long been the go to tool for Russian intel assets. By spreading disinformation to enough people, that information then gets forwarded by unsuspecting and easily fooled rubes to spread it to other rubes. Eventually you get enough bad info out there that people still think, even today, that Hillary sold uranium to Russians, broke the law with her email server, and committed all sort of other crimes (which of course is all false) and that effects the vote on election day.
