If we counted the vote by hand there would be no machine to argue over the inner workings. It is actually quite easy to do.
Actually, it would probably be much harder to count by hand.
In the 2022 midterms, Florida had over 10 election races on the same ballot, Governor, US Senate, US Congress, other statewide offices, local offices and over 10 constitutional amendments.
7.5 million people voted, conservatively 75-million-line items would have to be counted and totaled, if 1 or 2 races per ballot had to be counted then it would be relatively easy, but when it’s 10 or more, humans doing mundane things like count votes are prone to mistakes.
