The real problem isn’t that the Murdoch Boys are Leftists, but they are both married to died in the wool Liberal wives who are wagging their tails (If you get my drift).
I think they're taking Fox News to the Left of where it has been for 15 years.
If they go Left, I'm not sure what audience they expect to attract except to bleed off some from the existing liberal networks.
Because they sure won't get the loyal Fox News fans back if they go Left. And those fans will go where? OAN maybe? It's straight news with little commentary.
It'll be tough for someone to catch that firefly in the bottle again that Fox News Channel had for so long. There's an audience out there but to build a conservative network again with the right players and personalities is not easy. It will take time. And lots of money. Some big players will roll the dice maybe.
