I have not been able to verify any of the people in the article but I was able to verify one woman from a list I found in another post here. The woman's name is Julia Hooker, born in 1902, about a month older than the oldest human alive. So you have the ability to verify it, she was born in December and her zip code was 48234.

This is the first thing about the election I've really been able to verify. I've seen some of the weird stuff that we've been hearing about, but when I look for actual information to verify, I get absolutely nothing. Maybe I'm not good at looking, but I can't see any past vote counts in any of the states or anything of that sort.
