The drift began right after the Ailes meeting with the Obozo’s people. I also believe there was some emphasis put out by him that Fox would not be aggresive on the side of the GOP candidate. Every once in a while now, rather than every day, someone there does point out another Obama partisan screw up but nothing like a true anti establishment press would do.
Not only that, but when Murdoch turned it over to his son, and the Saudis partners exerting pressure about the same time, it really turned its coat.
What a crock.
