IIRC in either 2008 or 2012—maybe both—and definitely under the watchful eye of the NBPP (/s) there were precincts in which “voter turnout” was OVER 100%.
The one in Florida was a two page ballot. A few precincts in Cleveland were right at 100. There were some in Colorado that had more voters than people. And some others that were unexplained "glitches" https://www.wsbtv.com/news/local/fulton-election-results-show-more-100-turnout-4-pr/242919134/
