I believe the Dominion machine can make copies.
So the fraud went like this:
1) SET MACHINE TO TOSS OUT A HUGE NUMBER FOR ADJUDICATION.
2) ADJUDICATE IN SECRET THE TRUMP VOTE TO A BIDEN VOTE.
3) REPRINT THE NEW BIDEN BALLOT.
4) SHRED THE ORIGINAL TRUMP BALLOT.
That’s why he said he could tell the difference in where and what machine printed the ballot.
I still say they were shocked at the number of votes Trump got and they stopped counting to adjust their algorithm. Once that was done it was time to swap out and destroy ballots.
