What happens when the quantity comes up way short from processing the same ballot multiple times?
A part of the problem looks like the long time allowed for counting due to COVID and mail-in times is that it allows the fraudsters to gain access to voting lists to see who voted and who did not. The fake ballots can be assigned to someone who did not vote. There needs to be a large sample of people shown to have voted, but did not regularly vote in the past, where investigators go to their address and ask them in person if they voted.
