Yes, Fox is pulling to the 'center' to attract more viewers, especially at a time when many people who often don't watch the news are tuning in. That will leave them with the impression that they are more centerist than they really are. This is the same thing that the other networks are doing, but in the opposite direction.
Sorry to disagree, but FoxNews has gone left of center (except for Sean). A cable news stations worthy of Freepers no longer exists.
