Sean’s value is his line up of guests. It is they who many tune into, to hear. They are experts and respected conservatives.
Without them, I’m not sure of the numbers who would watch anymore, just for the pleasure of watching HANNITY run on with his hype and his emotions, alone.
As Bigg Red noted, his ego is a factor.
He simply will not respect time for his guests to but barely make a point, before Interrupting, and ALWAYS steals their work product by First giving to himself their work product, or their thesis, or their column titles, before he bothers tp introduce them, before they ever get to lay their own foundation. He already used their thunder for himself, in his blathering preamble to introductions.
But for his guests, his FOX ratings would be down around his ankles.
Precise description, Rita. He truly is loathsome.
