The company is more like a political science lab than a super PAC. It has tested thousands of messages with ads on TV and the Internet and social media postings. Only one in 20 of the tested messages is ultimately approved and run big time. The company is serious about testing its messages thoroughly before pushing them out everywhere. The company claims to have run 10 million voter surveys since January, of which four million were since Harris entered the race. Seems like a lot to us. Each message is ranked in its effectiveness in moving voters, and it is the survival of the fittest. Whichever company is getting the order for all the hard disks they are buying to store their data is surely doing well. The company has some very rich donors supporting their work, but they are rather shy about naming names.
