"What difference does it make!!"
Women currently make up 40% 0f the bread winners and therefore it's smart to use women on news stations as it draws them in, as they can relate, as well as men.
Megan Kelly is a beautiful woman and at the same time one of the most intelligent
news casters there is, imho.
Then there is Gretta Van Sustren, maybe not the most good looking woman, but again very intelligent, knows how to ask the right questions, and gets interviews that few others are able to get.
