Agree with your assessment completely. Back when I had tv, Greta was one of the hosts I respected the most on FOX. The best shows on FOX get the lowest ratings, and the worst shows on FOX get the best ratings.
Someone can correct me if I’m wrong (I don’t know how to locate the statistics), but I believe Greta continues to lead the way in her time slot, ratings-wise.
Perhaps someone will chime in with the correct information.
I do NOT believe Anderson Cooper has better ratings.
