Votes are voter fraud not outdated registrations
I do see a bit of a problem, though, in that voter registrations are not updated.
When I worked on Tammy Duckworth's campaign in 2012, they gave us lists of voters, and some of these registered voters were well into their 90's. Of course, when we called, the phone was either disconnected, or someone else had the number now and didn't know who we were talking about.
There should be a process where when a death certificate is issued, that person should be struck from the voter rolls.
