I have a few comments going back a couple of years predicting how electronic voting will cause civil unrest because it is so vulnerable to being discredited. Edward Snowden even recently tweeted a prof's video about the same thing. Everybody who had given the issue any serious thought at all already knew it was an inevitable problem. Luckily, the U.S. has a process for dealing with contested election results, and the parties will litigate it to its final state.
I'm just hoping for a very cold winter to keep people inside.
