The Rupert Murdoch I have known (and sometimes worked for as both journalist and lobbyist) is politically astute enough to know that calling for the dismissal of Peta Credlin ensured that Tony Abbott would keep her in the job as his chief of staff. A Prime Minister would not survive being seen to cave in to the public advice of his tweets. No. The cunning old fellow actually has Tony in his sights not Peta.
As I wrote on Tuesday: Be afraid Tony Abbott, be very afraid. The News Corp empire has determined that a Coalition government led by you will put Labor back in office and that would never do.
