Fox before 5pm only pretends to be R, so they can fool R's. They still tow the party line they just do it in a more deceptive way. After 5pm though you have the hosts who arn"t comped but are too popular to be simply replaced …yet.
Yes, I mean the owners of Fox intend to make the entire station leftist but they haven't had time to weed out the evening hosts without getting conservatives suspicious.
More of a reason to suspect this was a set up to implicate Q followers.
