Rupert Murdoch is a libertarian—against too much state control, and in favour of individuals taking responsibility.
For the record, I agree with everything that The Appalling Strangeness has to say on this—Murdoch may be an economic liberal but that is not the same as being a libertarian.
Economic liberalism is, in fact, only one half of the equation: a libertarian is also socially liberal and I have yet to see The Scum, for instance, backing the legalisation of drugs.
But worse than that—Murdoch is a corporatist. His rags back whichever party Murdoch thinks will enable his News Corporation to wield the most power. Further, he deliberately backs parties in a way that makes them grateful and thus more likely to serve his agenda.
In other words, Murdoch gains legal advantage for himself and his businesses through effectively buying the legislators—he is, as I have said, a corporatist.
And there is nothing libertarian about corporatism.
