Election officials have said that these errors being caught is evidence that they are really good at catching errors. But there are at least two good reasons to doubt this. First, these errors were all huge and it seems unlikely that people only make huge errors and never small ones, so the lack of stories about small errors suggests that they are actually pretty bad at detecting “errors”. Second, the sheer number of voter fraud convictions that have taken place, the rate at which non-citizens seem to vote, and the number of excess voters illegitimately kept on voter rolls, all seem to imply that, at the very least, this is a highly error prone process.
