I see a remarkable similarity between FNC and the Rupublicans in D.C.
The Republican come into power acting as conservatives. With overwhelming numbers in both the House and Senate (and the POTUS as well), the Repblicans want to 'broaden' their support by moving towards the center and left. They never, ever seem to realize that by moving away from the right, you numbers will go down as those on the left will never support and those you are leaving feel deserted.
A very good mirror between the two if I may say so.
You nailed it.
