In the Johnny Carson era of The Tonight Show, there were lots of comics, but also other talent and a wee bit of politics thrown in.
In the Gutfeld era, after prime-time programming seems to be mostly all politics with comedy stirred in, and a few non-political cultural or news topics tossed in.
Greg and company get pretty old with no other forms of talent on the show. Their narrow focus and round table style have passed their "use-by" date.
