Gutfeld's ratings declined for several reasons, not the least of which was most of his guests took jobs in the Trump administration! One of his cohosts, Kat Timpf endured a pregnancy and a diagnosis of breast cancer as she was giving birth and was off the show an extended time also. Gutfeld even took time off for the birth of his own child. Not bad for someone who is sixty years old!
Losing the Biden administration also cut down on their daily material. Now they make jokes of the Democrats like Jazzy Crockett, AOC, Swalwell, Schumer and Nancy. They still had the View providing material but even they took a hiatus. Throughout all that they still beat the stuffing out of the other late night hosts who got fired and suspended. All they had and still have is TDS-fueled Orange Man Bad.
It's obvious you never watch the show. Your TDS would not allow it.
