Not ‘hyper-targeted’. Cambridge Analytica never did that. The (non-technical) salespeople kept saying they were to impress (non-technical) campaign managers but there wasn’t anything like that.

The “Do so” is a far better example of what they really did: develop a talent for race-based dog-whistle type messaging that _anyone_ could see but where one group would respond differently. The main differentiator that Cambridge Analytica would introduce was Social media vs. traditional press to split messaging by age-group. They tried to improve it using magazine subscription and car brand (from credit reports) but it wasn’t much better than using party registration datasets.
