Don't know much if anything about internal US politics and whose job is what but the Russians are quite certainly exactly after sowing discord, division, hatred etc., what better way to weaken their enemies. You won't believe the amount of troll posts only in the comments under the news in Bulgarian news sites (95+% of all posts). Probably the same elsewhere, they _do_ have the troll factories and who know how many "subcontractors" etc., it is cheap. In Europe they push towards division between the EU states, boost as much as they can euroscepticism etc., by how much they have influenced the brexit vote is anybody's guess but they did push this way as strongly as they could. And then I remember once seeing something about Putin personally hating Hillary for some reason (not sure what it was and just "pretty sure" about the credibility of my memory though).
