Double-Blind Vote Counting

Votes lost in Carteret County, North Carolina.

Thinking about it, there are a number of different places that need to verified.

  1. is the vote stored the same as the vote displayed?
  2. is the vote printed the same as the vote displayed?
  3. is the vote stored the same as the vote printed?
  4. do the above match the vote entered?

The voter can verify that the vote printed and displayed match the vote entered, but only a count of both the printed output and the electronically stored vote can confirm that the voter is not being misled. The paper trail is not sufficient to ensure accuracy. Without it, accuracy is impossible.
