A mail in ballot is signed on the outside in Oregon. It thus has your name on it.

If they know your name then they know how you are most likely to vote. Data is available from voter registration databases, Google marketing databases and even Twitter and Facebook databases.

Given Big Tech data processing capabilities you might as well write “Republican” on the front of the envelope.

Every time you "like" something it is telling Big Tech and anyone who wants to buy their databases what you are. The words you use, who you communicate with, what you read, is collected. What products you are likely to buy and who you are likely to vote for is all valuable information that is bought and sold.

If they can see your name on the outside of the ballot envelope it is possible to electronically/mechanically thus sort them into bins: One for likely Democrat votes, one for likely Republican votes etc. Republican votes can be set aside, delayed in tabulation until irrelevant, substituted, spoiled, or lost.

In Arizona ballot envelopes were just "scanned" by Runbeck without observers before arriving at the election tabulation center. What information was scanned and was it used to sort the ballot envelopes into politically useful bins?
