From Jonathan Simon:
We know better than to put anything past them. That said, we would expect to find a few glitches out there. The pattern we would see if pro-GOP rigging was rampant would be a certain very small amount of visible vote flipping both ways (those would be the glitches) while the real rigging was invisible.
Vote flipping visible on the screen is a risky and rather stupid way to rig elections and there’s obviously no need for it; you can just program the invisible counter on the chip to “flip” the votes. Visible vote flipping can lead to voter frustration and longer lines and work as a “denial of service” attack, but that is small potatoes compared to the potential of flat-out rigging. It could also conceivably provide an excuse for “maintenance,” allowing technicians to recalibrate the rig.
And, finally, it could be a calling card left visible to show that it’s just “innocent” glitches (which go in both directions) and not systemic fraud, as the unilateral pattern in the past has led us to claim.
Who knows. I strongly doubt, however, that it’s a GOP attempt to bring pro-Democratic rigging to light. They have way too much to lose by triggering any additional public attention to this phenomenon on either side. If I had to guess, I would say these flips are either genuine glitches or perhaps programming mistakes on the part of inside manipulators who just screwed up their code.
I have hoped that at some point a white-hat hacker would come in and rig an election such that, say, one candidate got 25 million votes in a state like North Dakota with a tiny fraction of that population. That would certainly get some attention and should be easy enough to do. I wondered briefly whether the flips that have been reported were part of such an effort, but I doubt it.
