I have been both a Clerk and Judge of Elections, and I want you to imagine what would happen in NYC if NY State adopted the same procedures being used this November in Colorado: Many of these '164 year olds' are, in fact dead. In CO, a ballot would be mailed to their last known address. It would very likely be cast and returned. At that point there is no way to invalidate it. The same thing can easily happen in many precincts in NYC, Chicago, Philadelphia, ... where there is no one effectively supervising the live vote, and the same person is able to vote multiple times with what are actually defunct registrations.
Let me tell you what else they do in those jurisdictions. They deliberately show up at the wrong precinct with a defunct registration; pretend to be confused, pretend not to speak English, pretend they can't get transportation to the correct precinct, or have some other act. They're then allowed to vote in the wrong precinct. The vote goes into the provisional ballot set. Guess what? It's verified as being a registration in the other precinct, after the fact, but there is now no one who might know the voter who can verify the ID. There is now no one present who can say -- hey, that 73 year old woman voted an hour ago.
The point that too many people are missing here is that election officials deliberately falsified part of the voters identity. What other parts could they have falsified?
