How can anyone know if political lies and memes on facebook effected an individual voter? Over 100 million people saw tainted untruth statements, memes and lies that were biased toward Trump on facebook alone. The Russians were on instagram, facebook, twitter and every other major form of communication in America. Hundreds of millions, perhaps billions of comments, posts, memes and things that seemed to suggest Americans were voting toward Trump.
The 2016 election was one of the closest in history. We will NEVER know what effect they had.
This, is how the Russians operated. They were not in voting booths.
