By hacking and dumping emails, Russia is trying 'to denigrate the American electoral system, to make it look chaotic, make it look manipulable, make it look subject to intrusion, cheating and vulnerable so you can't trust it...to make us look no better than the Russian electoral system.
I'm going out on a limb here, but wouldn't that impression be the actual truth? How the democrats rigged against Sanders, that apparently the Democrats and their candidat got hacked, we know for ages that voting machines are not trustworthy, there is the concept of gerrymandering, and how on earth became Trump even a candidate, not speaking about that the charges against Hillary were dropped.
Not sure whom to attribute those hacks, but isn't it actually a good thing, that this knowledge is now spread between the voters so they can make a more informed decision? Isn't it better to know what is going on than to life in fluffy unicorn land?
All the governments are always saying: No need to fear, if you have nothing to hide. Well...
