When the facts are on your side, argue the facts. When the facts are against you, attack the person. Why do you think she decided to start out attacking his credibility instead of discussing the facts? Exactly, you have to hand it to her, she is extremely intelligent. Intelligent, but not smart.
This may work with the typical person that doesn't do much thinking about the arguments presented, but It may back fire with the typical FOX viewer.
My guess is a substantial portion of FOX's audience is made up of people who can see past this type of tactic. They got tired of seeing the spin on other stations. FOX built its audience by "presenting the facts, and letting the audience decide".
I would say 'Intelligent but not able to conceal her SUBJECTIVE involvement'..Of course many could see exactly what she was doing. However, all FOX cares about is ratings. As long as she can produce drama like she did last night, she may stay. I had decided I couldn't stand her voice, but decided to see what ole Dicky-poo had to say when the action started. I notice she has Pat Buchanan scheduled tonight when everyone will be watching the Olympics...hmmm
