Is it mandatory that all news anchors lose their minds right at the end of their careers?
It is mandatory for them to lose it (and become liberal automatons) in order to succeed. It is long gone long before the end of their careers.
No. I give you Dan, as evidence that they can also do so in the middle. Honest to God I stopped watching him entirely years ago. Not because of the liberal bias, but because he was freaking me out. There were to many WTF moments, culminating with the heavy sweaters and "Courage!".
