If it doesn’t happen on every machine then it’s just a touchscreen calibration problem. If it was programmed to always select zero it would be happening on every machine.
Dumbest thing I ever heard of using touchscreen pcs for voting.
The Dems are not that stupid.
If they have one or two machines doing this, and the vote is tight, these machines can help get them the needed votes to steal the election.
If every machine did this even the Lame Stream Media would have to report it and then everyone would know. Having a single machine do this in every precinct would still allow the Dems to hide behind the "calibration" issue.
