Been saying that for years; electronic voting is much, much easier to manipulate - at the machine, ward/precinct, state or national level than physical ballots.
For months, I predicted that the Brexit vote would fail - until, that is, I found out that they were using physical ballots. Apparently, a fair number of Brits had their doubts as well, since so many of them voted in pen vs. pencil...
That is why there is vote fraud organizations such as “True The Vote” that fights and prevents voter fraud.
