Where I live any ballot can be traced back to a human, and verified.
There is a sort of "data collection" computer at the polling locations, but the ballots are saved and could later be manually check.
I don't think anything like this is the case in the states that just sent millions of vote-by-mail ballots out.
You're wrong.
The problem is, the officials are democrats,
And republicans.
And the US attorneys assigned to monitor the election for fraud, all Trump appointees.
