Fox & Friend's decline has nothing to do with Carlson IMHO. She is obviously a beautiful woman and is certainly intelligent and very well credentialed. She doesn't have the same camaraderie with Brian & Steve as E.D. Hill. But who would?
The problem is it's tilt towards air-headed segments. For years I TIVO'd F&F every morning just to make sure my main tube was on the Fox News channel when I turned it on. Then I started noticing F&F and watched it. Lately I find myself fast forwarding through more portions of it, or not watching it at all, but it's not because of Gretchen. The producer is becoming weak.
I personally don't like Martha on The Live Desk at noon here, but I like the format, content and the way it's produced, so I watch it during lunch.
Elisabeth is a genuine air-head with "survivor" credentials. And to make matters worse isn't good looking.
