Half are real? Clearly, the Bee doing satire.
I was thinking exactly the same thing, and then realized I needed to focus on the last line--which is the depth charge:
"At publishing time, the auditors discovered that they had just accidentally reviewed Biden's votes for the 2020 election instead. They apologized for their error and confirmed that only half of the votes cast for Biden are real and the number of his Twitter followers remains unknown."
And of the real half, none have any connection to reality.
