This seems to me like the most useless study that was ever conducted. Is there was no requirement to show ID, how do you know which people were impersonating someone else. Those seven instances were instances wherd people that got caught. But if you’re not actively looking to prevent impersonation, how do you know the people are doing it?
Your 2nd place in the most recent election comment was a statement of such stupidity it took me a little while to realize what you were talking about. If the election was dependent on winning the popular vote you would have a point. But since it’s not this is just an extreme case of saltiness.
