“Said he could audit 500K ballots in 2 hours.”
And the slobs that counted the ballots took days?
That in and of its self is a sign the system was manipulated.
To add some detail....
He is specifically referring to the paper absentee ballots and not the machine ballots from the voting machines via the in person vote. Just wanted to put the focus on the target universe.
The several hundred thousand ballots scanned in the very short time can detect artifacts related to ballot printing, folding, mail processing, machine signatures, etc. that are related to various kinds of forgery. Some other means of analysis I think would be slower as I suspect they would be more manual to look at things such as ink and paper types.
