Here's the 200 data points CA wanted to give to David.

But what was particularly problematic for Carroll was that, he believes, the profile the company sent him wasn’t nearly comprehensive. Nix and other Cambridge Analytica executives have boasted that the company has up to a startling 5,000 data points on each of the 230 million voters in the US. What Carroll received in March, according to his tweet at the time, was about 200 data points, and, even then, it wasn’t clear how or where the company got the data or who it was shared with, beyond the vague descriptions in the letter.

I vaguely recall people dismissing CA before so I have my doubts about their efficacy, but it is a reminder that this is the age we live in.
