We use voter ID. At the registration level. I don't understand how none of you understand this yet? You prove your identity when you get registered.
Rant: Surely no one is so stupid as to think that people just show up at the voting booth and no one checked their identity prior to that day.
Do people really think that you just tell the government that you want to vote in some random state and the government just says "Ok, go ahead," without verifying that the person making the request is who they say they are and lives where they say they live? Anyone who is believing that probably shouldn't be voting either, lol.
This thread is about a voter registration system designed to catch bad registrations, regardless of why, and is doing so effectively. The OP is pointing to a system that works as evidence that there is a problem elsewhere. It's doubly idiotic. The system flags bad registrations. If the registrations are bad and flagged then those individuals aren't registered to vote. That means they're not going to be able to vote in the election.
It's like complaining about food poisoning even though the quality check at the restaurant found and removed contaminated food before anyone could eat it. No one was poisoned but because the quality controls work, that's proof that the diners are being poisoned? It's just stupidity.
