As has been shown, it's a lot easier to hack voters themselves with targeted information, misinformation and outright fantasy. We've also learned something amazing this cycle: a key tactic anyone will replicate in the future:
When you run negative political ads, don't let anyone outside of the laser focused target demo you want to reach see it until it's too late. The "super predator" ads were crazy damaging to HRC in swing states, but even to this day most people haven't seen them. There's no way to respond to political attacks you aren't even aware of.
Heh. We call those elections, and this is nothing new.
In Hillary's case it's even more absurd to claim that they could have known nothing -- many of the voters targeted and flip flopping were union guys and easy to get intel out of. End of the day, the campaign fucked up.
I come from New York, where we had easily manipulatable, gear-driven mechanical machines for decades. (It was pretty trivial to jam them up, and the historical over representation of the number 9 in results validated that) The major parties understood the margin of error and used absentee balloting to cover that risk.
I don't think there is any indiciation in my post that HRC didn't screw up a campaign in several key ways. It's just worth noting that there is a new and unique series of technology-enabled techniques that DJT's team used to influence key states at the end.
Hopefully Facebook will be forced to release all the relevant data and we can see more about it.
