This is hardly true of the Kochs. When David Koch ran to the right of Reagan as vice president on the 1980 Libertarian ticket (it polled 1 percent), his campaign called for the abolition not just of Social Security, federal regulatory agencies and welfare but also of the F.B.I., the C.I.A., and public schools  in other words, any government enterprise that would either inhibit his business profits or increase his taxes. He hasn’t changed. As Mayer details, Koch-supported lobbyists, foundations and political operatives are at the center of climate-science denial  a cause that forestalls threats to Koch Industries’ vast fossil fuel business. While Koch foundations donate to cancer hospitals like Memorial Sloan-Kettering in New York, Koch Industries has been lobbying to stop the Environmental Protection Agency from classifying another product important to its bottom line, formaldehyde, as a “known carcinogen” in humans (which it is).

Tea Partiers may share the Kochs’ detestation of taxes, big government and Obama. But there’s a difference between mainstream conservatism and a fringe agenda that tilts completely toward big business, whether on Wall Street or in the Gulf of Mexico, while dismantling fundamental government safety nets designed to protect the unemployed, public health, workplace safety and the subsistence of the elderly.

Yet inexorably the Koch agenda is morphing into the G.O.P. agenda, as articulated by current Republican members of Congress, including the putative next speaker of the House, John Boehner, and Tea Party Senate candidates like Rand Paul, Sharron Angle, and the new kid on the block, Alaska’s anti-Medicaid, anti-unemployment insurance Palin protégé, Joe Miller. Their program opposes a federal deficit, but has no objection to running up trillions in red ink in tax cuts to corporations and the superrich; apologizes to corporate malefactors like BP and derides money put in escrow for oil spill victims as a “slush fund”; opposes the extension of unemployment benefits; and calls for a freeze on federal regulations in an era when abuses in the oil, financial, mining, pharmaceutical and even egg industries (among others) have been outrageous.

The Koch brothers must be laughing all the way to the bank knowing that working Americans are aiding and abetting their selfish interests. And surely Murdoch is snickering at those protesting the “ground zero mosque.” Last week on “Fox and Friends,” the Bush administration flacks Dan Senor and Dana Perino attacked a supposedly terrorism-tainted Saudi prince whose foundation might contribute to the Islamic center. But as “The Daily Show” keeps pointing out, these Fox bloviators never acknowledge that the evil prince they’re bashing, Walid bin Talal, is not only the biggest non-Murdoch shareholder in Fox News’s parent company (he owns 7 percent of News Corporation) and the recipient of Murdoch mammoth investments in Saudi Arabia but also the subject of lionization elsewhere on Fox.

No less a Murdoch factotum than Neil Cavuto slobbered over bin Talal in a Fox Business Channel interview as recently as January, with nary a question about his supposed terrorist ties. Instead, bin Talal praised Obama’s stance on terrorism and even endorsed the Democrats’ goal of universal health insurance. Do any of the Fox-watching protestors at the “ground zero mosque” know that Fox’s profits are flowing to a Obama-sympathizing Saudi billionaire in bed with Murdoch? As Jon Stewart summed it up, the protestors who want “to cut off funding to the ‘terror mosque’ ” are aiding that funding by watching Fox and enhancing bin Talal’s News Corp. holdings.

When wolves of Murdoch’s ingenuity and the Kochs’ stealth have been at the door of our democracy in the past, Democrats have fought back fiercely. Franklin Roosevelt’s triumphant 1936 re-election campaign pummeled the Liberty League as a Republican ally eager to “squeeze the worker dry in his old age and cast him like an orange rind into the refuse pail.” When John Kennedy’s patriotism was assailed by Birchers calling for impeachment, he gave a major speech denouncing their “crusades of suspicion.”

And Obama? So far, sadly, this question answers itself.
