They got over confident and fucked up. Probably even tried to rig it a bit and there was overwhelming support (silent majority type thing). Now that Brexit happened, I think they'll be doubling down on the US elections.

What we need in the US is a private (changes every election) vote # that's handed out to every citizen after the election, and a giant list of the votes and vote #. That way your employer can't ask for your # before you vote, but you can just give them a fake one that leads to a vote for whomever your employer favors. And it allows you to look up your vote, to see if it's the way you voted.
