Sequioa Vote Systems (and Smartmatic) which is now Dominion
The AVC Advantage contains a computer. If someone installs a different computer program for that computer to run, it can deliberately add up the votes wrong. It's easy to make a computer program that steals votes from one party's candidates, and gives them to another, while taking care to make the total number of votes come out right. It's easy to make this program take care to cheat only on election day when hundreds of ballots are cast, and not cheat when the machine is being tested for accuracy. This kind of fraudulent computer program can modify every electronic "audit trail" in the computer.
That would count out a lot of leftists who can't spell.... Hahahaha good
Personally, I think the poll workers cheated their asses off, and Dominion already had an algorithm in place to steal the election. One left hand not talking to the other left hand, created way more votes than anticipated. Had just one of those commie left hands not attempted to cheat, we likely wouldn't have seen nearly the results we did. Thank the heavens the commie left hands went all in on their massive efforts.
I think they did it on purpose, so that they have more cheats than we have time to reject. If it takes 2 weeks to get rid of the double-counts, and 2 weeks to get rid of the fake mail-ins, then we run out of time to address any of the dominion fraud or the shredded trump ballots...
Also, using different means allows them to deny coordinated effort.
I think whoever is pulling strings may have told key people in those states they needed to cheat and allowed them to use the methods they used historically and were comfortable with. Gave them the desired endstate and allowed the subordinate to figure out the best way to reach it.
I think the ability to switch votes with the software was a fail safe to use in an emergency if it looked like Biden wouldn't win. The jumps in Biden votes in MI and WI looks like a less sophisticated emergency action and they were just hoping the media would cover for them.
