So now we have it: what appears to be hard, irrefutable evidence of Rupert Murdoch's ultimate and most audacious attempt – thwarted, thankfully, by circumstance – to hijack America's democratic institutions on a scale equal to his success in kidnapping and corrupting the essential democratic institutions of Great Britain through money, influence and wholesale abuse of the privileges of a free press.

In the American instance, Murdoch's goal seems to have been nothing less than using his media empire – notably Fox News – to stealthily recruit, bankroll and support the presidential candidacy of General David Petraeus in the 2012 election.

Thus in the spring of 2011 – less than 10 weeks before Murdoch's centrality to the hacking and politician-buying scandal enveloping his British newspapers was definitively revealed – Fox News' inventor and president, Roger Ailes, dispatched an emissary to Afghanistan to urge Petraeus to turn down President Obama's expected offer to become CIA director and, instead, run for the Republican nomination for president, with promises of being bankrolled by Murdoch. Ailes himself would resign as president of Fox News and run the campaign, according to the conversation between Petraeus and the emissary, K T McFarland, a Fox News on-air defense "analyst" and former spear carrier for national security principals in three Republican administrations.

All this was revealed in a tape recording of Petraeus's meeting with McFarland obtained by Bob Woodward, whose account of their discussion, accompanied online by audio of the tape, was published in the Washington Post – distressingly, in its style section, and not on page one, where it belonged – and, under the style logo, online on December 3.
