So for your idea to work Auntie Rose would have to check her own vote...right? If she didn't then nobody would know. Somehow you think only Auntie Rose would be able to use her "vote wallet" and nobody would be able to obtain the credentials to vote in her name. Sounds unlikely.
"Nobody follows the rules"? So how do republicans ever win elections? Or are you saying republicans are cheating as well? In reality, I just don't believe that you didn't sign the poll book.
