I found two still alive for sure. I cant verify any deaths with certainty. And I think those listed as born in 1900 might be typos in their registration database. The fact that one is still alive certainly means these are not ALL dead voters.
I am using Microsoft Excel in order to look over the data, that is Michigan registered voters at, or over, the age of 100 years.
This will take a while, but an example of what I am finding:
Zip Code: 48221 / Age 100 or older (count): 271 / Detroit, Michigan / County: Wayne / Neighborhood: Bagley
Zip Code: 48238 / Age 100 or older (count): 239 / Detroit, Michigan / County: Wayne / Neighborhood: Winter Halter
So, in merely those two zip codes, there are 510 registered Michigan voters aged 100 or greater.
There must be a fountain of youth in Detroit, and the Democrats have been keeping it a secret.
