In 1995, Murdoch's HarperCollins famously offered newly minted House Speaker Newt Gingrich an enormous $4.5 million book deal -- around the same time that Murdoch and his lobbyist were meeting with Gingrich to discuss the serious FCC challenge Murdoch faced regarding whether Fox Broadcasting was foreign owned, in violation of U.S. broadcasting rules. Facing bipartisan criticism of the deal, Gingrich retreated and settled for a token $1 advance in addition to sales royalties.

Nader must be aware that Murdoch uses publishing contracts to aid his allies. During the 1995 Gingrich controversy, Nader wrote a long letter to Rep. Nancy Johnson, R-Conn., then chairwoman of the House Committee on Standards of Official Conduct, demanding that she authorize an independent counsel to look into the book contract.

In 1998, HarperCollins made headlines again when it unceremoniously dropped from its list the memoir of Christopher Patten, the last British governor of Hong Kong, whose book, "East and West: China, Power and the Future," was critical of the communist government in Beijing. Patten was initially informed that his submitted chapters did not meet HarperCollins' "expected standards." But internal News Corp. memos published by London's Daily Telegraph made it clear Patten's book was dropped out of concern that its harsh tone might damage News Corp.'s burgeoning business dealings in the Far East. Patten sued for breach of contract and settled out of court for an undisclosed sum.

That same year, Murdoch ordered Fox Television to abandon its planned production of "Strange Justice," a drama based on the book of that title by the New York Times' Jill Abramson and the New Yorker's Jane Mayer about the confirmation of conservative Supreme Court Justice Clarence Thomas. (It was subsequently produced and shown by Showtime.) According to a New York Times report, Murdoch told an associate that Thomas was a friend of his and that he had been railroaded during his confirmation hearing.

Nader's previous book, 2001's "Crashing the Party: How to Tell the Truth and Still Run for President," posted modest sales numbers for its publisher, St. Martin's. The hardcover sold 27,000 copies, according to Nielsen BookScan, which tabulates sales. The paperback version in 2002 sold just 17,000 copies, as interest in Nader seemed to wane. In late 2000, the New York Post reported that Nader had landed a book advance for "Crashing the Party" worth roughly $200,000. If true, it's unlikely St. Martin's made much of a profit from sales of 44,000 copies. Nader had an option for another book at St. Martin's, but it had expired by the time he was ready for his next book. That meant Nader was free to shop for a new publisher for "The Good Fight." Nader's literary agent could not be reached for comment.

Now Nader has found a new home at HarperCollins' ReganBooks imprint. "Nader is a presidential candidate with an interesting background, and that alone was the reason we published the book," says Paul Olsewski, vice president and senior director of publicity for ReganBooks. Citing a company policy, he would not comment on how much ReganBooks paid for Nader's book.

Nader is an unusual writer for Judith Regan, former Fox News talk show host and president of Murdoch's ReganBooks, to acquire. The firm's recent political nonfiction titles read like an in-house reading list for News Corp.: "More Than Money: True Stories of People Who Learned Life's Ultimate Lesson," by Fox News' Neil Cavuto; "Deliver Us From Evil: Defeating Terrorism, Despotism, and Liberalism," by Fox News' Sean Hannity; "Hating America: The New World Sport," by Fox News' John Gibson; "Rewriting History," by Dick Morris, Fox News commentator and columnist for the Murdoch-owned New York Post; and "The Connection: How al Qaeda's Collaboration With Saddam Hussein Has Endangered America," by Stephen Hayes, writer for Murdoch's Weekly Standard. Among the Murdoch imprint's best-selling titles was Bernard Goldberg's rant against the so-called liberal press: "Bias: A CBS Insider Exposes How the Media Distort the News."

While ReganBooks did publish Michael Moore's 2002 anti-Bush bestseller, "Stupid White Men ... And Other Sorry Excuses for the State of the Nation!" it was only after Moore publicly accused the publisher of trying to censor the book by forcing him to cut passages deemed too critical of Bush. Last month ReganBooks hurled a big spit wad at the "Fahrenheit 9/11" filmmaker with a new book titled "Michael Moore Is a Big Fat Stupid White Man."

Nader's "The Good Fight" will not only benefit from the P.R. muscle of Murdoch's publishing arm but will also receive generous airtime on New Corp.'s television and radio outlets. "The big question will be, Does Murdoch promote the book on Fox?" says Pingree at Common Cause. "Fox has made it clear who they'd like to see in the White House. So if Fox promotes Nader's book, then that's more of a story than Harper's deciding to publish it."

According to Nader's book tour schedule, he makes two appearances on Fox News this week and also appears on Fox News Radio and on Hannity's daytime radio show. That compares with a single TV appearance on Fox News by Nader during the previous 120 days. "Fox never cared about Nader, or the issues he championed," says Jeffrey Chester, executive director of the Center for Digital Democracy.

But now, Nader's book presents a unique synergy of politics and profits for Murdoch. "It's a win-win for him," says Consumers Union's Kimmelman, who during the early '80s worked for Public Citizen, a public advocacy group founded by Nader. "Murdoch's making money by promoting the book on Fox, and if Nader draws a strong audience, it may benefit reelecting George Bush, which would mean a favorable environment for further deregulation of Rupert Murdoch's media empire. As an entrepreneur, you can't ask for anything more; he's making money on both ends."
