Where this writer stands

No opinion piece by this writer has been scored on a policy topic yet.

Only opinion columns and editorials are scored. Each piece is read twice by a language model, which records the author's own stance on a policy topic only where the piece argues one, with a quote that must appear in the piece. An author's position on a topic is the average of their pieces, weighted by the model's confidence. News reporting is listed but never scored.
