Enough already. Thankfully, the big 3's influence has diminished, but I find it sad, that these 3 guys have been the major source of news for most americans for close to a quarter of a century.
If President's can be term limited, so should anchors. 8 years, and it's time to get a new warm body there. There is a certain cynicism inherent in being a top dog all the way since the first Reagan term. I think it is obvious in the way they cover the presidency. I would rather have some somebody who is 35 now take the job until they are 42. They make enough money so they can retire, write their memoirs, or teach at that point.
