She was "sexy", but "too much hard work." I'm a regular Fox & Friends viewer (mostly in protest of the other insipid morning programs like Today and Good Morning America) so over the years I've gotten to know Gretchen Carlson pretty well. Stuck between Steve and Brian she always seemed a prudish scold with an irritating, self-righteous demeanor that I simply put up with because I figured some people in the Fox audience actually liked her persona. It was obvious that Steve and Brian did not, but they were stuck with her like so many talking heads and had to make the best of it - which they did. Besides, she was no worse than any of the other women on morning show TV - I mean, you're only going to find a certain kind of person to do this kind of work and that kind of person is the Gretchen Carlson kind. Then, one day, she was gone and replaced by Elisabeth Hasselbeck and the F&F ratings began to climb, and climb and climb - in two months view
