Since the 1990 election cycle, Murdoch has contributed about $750,000 to federal candidates and political committees, according to research by the Center for Responsive Politics.
Of that sum, 80 percent -- or $600,200 -- has benefited Republican candidates and committees, including a $250,000 contribution to the National Republican Senatorial Committee during the 1990s, when the committee could still accept unlimited "soft money" donations.
Meanwhile, 12 percent of the donations, or $90,300, benefited Democrats, according to the Center's research. The remaining $57,500 went to corporate political action committees -- namely those of News Corp. and Philip Morris.
The top recipient of Murdoch's money among Democrats is Hillary Clinton, who received cash from Murdoch during her time as a U.S. Senator from New York. She received $4,200 from Murdoch during the 2006 election cycle and $2,300 during the 2008 election cycle.
But that's less than half of what the top Republican politician to get cash from Murdoch has received.
