It was a column error in tabulated election results that cause all the conflict in 2020 in Antrim county, Michigan. Any computer folks who took the time to read the report by an University of Michigan computer scientist hired by the Republican chaired bipartisan committee that the Michigan state senate would have seen that there was no vote fraud, but user error that got caught almost immediately in the accountability systems that were in place to catch any errors like that.
If we stopped trying to report election returns in real time like sporting events, and could be patient a few hours, we could avoid a lot of these highly divisive controversies.
