Ann Coulter with Bill O'Reilly: Losing sales because of shift in societal tastes?

An article in business magazine Portfolio notes that “Though never exactly shy, Ann Coulter has been especially noisy in her self-promotion [of a new book] lately” and asks: “Could it be because she’s worried she’s losing our attention?” Or, that is, that she isn’t selling books like she used to? Reporter Jeff Bercovici notes that “Coulter’s latest book, Guilty: Liberal “Victims” and Their Assault on America, is something of a misfire by Coulterian standards,” selling far below the numbers she’s used to getting — such as her 2002 title Slander: Liberal Lies About the American Right, which sold 333,100 copies, plus another 108,300 in paperback, or her 2003 book Treason: Liberal Treachery from the Cold War to the War on Terror, which sold 396,600 copies in hardcover. Asks Bercovici, “Could it be that Barack Obama‘s America has a smaller appetite for Coulter’s brand of take-no-prisoners, obey-no-logic conservatism?”
