Here's some stuff from Media Matters:
Summary: A WorldNetDaily.com article about author Jerome Corsi's forthcoming book, The Obama Nation, asserts that the book "points out" that "Barack Obama admitted using drugs in his autobiography but never revealed if or when he stopped." In fact, Obama wrote in his autobiography, Dreams from My Father, that he "stopped getting high" shortly after moving to New York City to attend Columbia University.
Promotional materials by Simon & Schuster for author Jerome Corsi's recently released book, The Obama Nation: Leftist Politics and the Cult of Personality, echo Corsi's false claim that Sen. Barack Obama's Global Poverty Act of 2007 "would commit the U.S. to spending 0.7 percent of Gross Domestic Product on foreign aid." Simon & Schuster's materials falsely assert that Obama has a "radical plan to tax Americans to fund a global-poverty-reduction program."
The Simon & Schuster release also states that "n this stunning and comprehensive new book, the reader will learn about ... Obama's naïve, anti-war, anti-nuclear foreign-policy, predicated on the reduction of the military, the eradication of nuclear weapons and an overconfidence in the power of his personality, as if belief in change alone could somehow transform international politics, achieve nuclear-weapons disarmament." In his book, Corsi asserts that "Obama embraces a 'no nukes,' antiwar, antimilitary posture that places him even further left than Senator George McGovern." But contrary to Corsi's characterization of Obama's views on nuclear weapons as far left, in an essay, published in the January 4, 2007, Wall Street Journal, former Secretaries of State Henry Kissinger and George Shultz, Hoover Institution senior fellow William J. Perry, and former Sen. Sam Nunn (D-GA) proposed nuclear weapons policies similar to those Corsi quotes Obama supporting.
