So, this application creates a ballot in real time dynamically. Pause the video at 13:45 mark and take a look. You fill in your:
email address
choose an id: SS, DL, or Passport
give the number for that id
select a candidate
click register and vote.
The application returns an encrypted string, save it somewhere safe. When you want to recall your ballot, fill the form out again with that encrypted string and you will get back your ballot. Even if someone knew your email, id they cannot get back your ballot without that encrypted string that you saved somewhere safe like a usb drive.
You should have listened to me supported this. Now we are going to repeat another stolen election because all elections, electronic or paper, have no receipts, so you will never know for sure if your vote was ever counted.
