So I voted today using my mail in ballot. It said don't sign the ballot because if you do, it won't be counted because you have identified yourself. Then you stick it in a yellow security envelope with the admonition to not identify yourself on the security envelope. I placed my yellow security envelope inside the white Official Ballot envelope. Licked it shut and then noticed a little flap that can be pulled open with this printed on it: "Do not remove this piece. It is here to protect your privacy." That is on the left. On the right is my preprinted full name and address.
