Well, you can't argue with the existence of the "troll factories". There definitely are paid people online who pursue the Kremlin propaganda, sometimes in not-so- subtle way. Were they in favor of Trump rather than Clinton? Probably, as the former expressed some surprisingly positive words towards Puting and the future relationship with Russia. Did they actually manage to interfere that much the public opinion? I'm not sure. I talk to Trump supporters almost every day. Their views don't seem much to do with Russia-sponsored propaganda. They are just unhappy with something (and this "something" is usually "the left" as a whole, or some aspect they don't like).
