She had, apparently, a nervous breakdown after the last debate and simply disappeared for a short time. No self-respecting journalist would hijack a national issue and become the story. It is unseemly and very unprofessional.
Roger Ailes thinks she is a journalist. He thinks Greta van Susteren is a journalist. He thinks Hannity is a journalist.
Murdoch needs to find someone else to run Fox.
Cable News networks (MSNBC, CNN, FOX, etc.) are not news networks, they are entertainment networks. Fireworks flying makes for great reality show style entertainment.
