I had a glance and didn’t see anything but I’m not investigative reporter and it’s hard to tell without spending a lot of time on it. One of the founders ran as a conservative and is now on the board. It’s probably in their interest (they are public/in stock market) to conduct good surveys, but to also generate data which would be of interest to conservative leaning organizations. That’s my guess. Their articles may be misleading though, since those would be more promotional/marketing material of the data they want to sell.
