Do you understand what year over year means? Of course ratings are down for Fox compared to the week of the election, Just like ESPN's ratings are down after the Superbowl. But Fox's ratings are higher than they were before the election, so that just means the temporary election viewers are gone, but their core audience is even bigger than it was.
“their core audience is even bigger than it was”
More than likely Fox is now getting liberals to tune in since the network leans more left than in years past.
Fox’s conservative viewers are leaving.
