Politics and Journalism have always been a little 'you scratch my back, I'll scratch yours'. They both need each other to exist, and yet feign like they can't stand each other at the same time.
Or with Murdoch it's BIG, not little. For example, after all Murdoch newspapers in Australia (which is most newspapers) went for one political party. That party won the election, and afterwards Murdoch got almost a billion $ tax cut from the government that was elected. Similar tactics are used all over the world, and he switches sides too.
