So, anywhere in the article does Barr explain the anomalies seen in the voting results data? If he doesn’t give a plausible counterpoint, then he is full of the bulls excrement.
The Dr. Frank claim assumes that the tabulators have access to voter rolls, but tey don't. The Shiva claim is just wrong, the same curves are visible in the Biden votes vs full ticket data. There are certainly explanations for the 94% or 97% Biden drops. But those are fraud, not counting machine algorithms. Some are rewritten ballots, some are fake ballots, some are double feeding, etc.
There might be counting algorithm biases. But nobody has shown any proof.
