Listen.... listen. This is all I'm going to say on this. Partially because it's dangerously close to off-topic for this forum, and partially because I really just don't want to spend additional time on the topic.
There is zero doubt that the exploitation of voting demographic research to produce a desired outcome is a common tactic. There is also little doubt that most young people skew predominantly liberal (arguably for Utopian/idealistic reasons I will not venture into in this thread). Furthermore, there is little doubt that Russian individuals -- just like domestic political operatives, activists, and special interests groups -- used a variety of avenues to inflict their influence upon the election. Therefore, it is not entirely ridiculous to presume that any activity originating from the vicinity of an interested party (activist, special interests group, Russian operative) might carry an ulterior motive in its timing given the circumstances.
But the point is that exactly the same claim could be made about practically any activity that might be somehow associated with any of these groups should its timing agree with that of some significant event (e.g., Election 2016). And the bigger point is that it's not doing anyone any good to try and connect those dots, even if there is some shred of a chance that the picture it paints carries some truth.
What we need to be doing today is examining our situation and learning from our mistakes. Because, you see, to paraphrase the ever-eloquent Stephen R. Covey haphazardly, not everything is someone else's fault. Blaming external factors for the failings of an ideology or even an entire political system is not a productive activity. Rather, the questions we should be asking are much more introspective in their nature: Why was Trump elected? What can we learn from this event? How can we prevent this sort of thing from happening again?
Because right now, as we speak, I personally believe he is headed for yet another victory in 2020 -- that is, if he isn't somehow removed from office before then.
