 You can't just use signature matching anymore. You can't just sign the ballot and now it's signature matching. It said that you have to use your ID number. You have to include your ID number with your ballot. So people did. They included their government ID number, driver's license or regular government ID. They just wrote their government ID number on the mail-in ballot. And now it's easier to verify them. Signature matching, it turns out, is a crappy system because it relies on election officials just staring at signatures going, eh, that doesn't really match. What are you, a handwriting expert?
