1/ I get questions frequently from people who have heard the SOS say that the BMD QR code ballots can be audited to tell who won. I'll explain why he is wrong.

Your BMD ballot vote is stored in the barcode. The text doesn't count. The computer reads only the QR code.

2/ The printer is supposed to print a candidate's name that matches what you entered on the touchscreen and what you hope the QR code symbol stands for. But you don't know whether the name matches the QR code.

So you really don't KNOW who you cast your vote.

3/ That can be overcome IF two unlikely things happen:
--every voter thoroughly and accurately checks before scanning to be sure that the printed list reflects his choices. (Hard to do, to remember all the contests), AND
--there is a thorough post election audit.

4/ Reality --very few people check their ballots before scanning. Therefore those are untrustworthy source documents for auditing.

If you pressed the screen for candidate Sam, but the printout & QR code said "Mary," and you didn't check, then your Mary vote was not intended.

5/ But auditors would never know that you pressed screen for Sam. The official record says Mary. The bug that changed your vote goes undetected. No one knows that your vote was recorded wrong.
