Murdoch is the powerful chairman of the News Corp, which includes in its vast holdings the Fox News channel, The Post and, most recently, The Wall Street Journal. Some of his media outlets have been criticised for conservative bias, having made a sport over the years of tearing into former President Bill Clinton and Hillary Rodham Clinton, among other Democratic leaders.

But an analysis of campaign contributions from employees of the News Corp and its affiliates, including 20th Century Fox, Fox Sports and the like, reveals they skew heavily Democratic and toward Clinton, who collected more than $100,000 in donations, compared with about $80,000 for Obama.

The records show that the employees gave less than $20,000 to Republicans seeking their party’s presidential nomination.

Last year, even Murdoch contributed $2,300 to Clinton’s presidential campaign. This followed The Post’s endorsement of her re-election in 2006, as well as Murdoch’s highly publicised fundraiser for her.

Several Murdoch advisers are close to the Clintons. Peter Chernin, president and chief operating officer of the News Corp, is a major fundraiser for Clinton.
