Fewer buyers for Ann Coulter's latest?

Is Ann Coulter worried she's losing our attention?, asks Portfolio.com.  The business site points out that sales of "Guilty," the conservative polemicist's latest book, are not keeping pace with past efforts.

Of course, success is a relative term. Nielsen BookScan says that in the two months since its release "Guilty" has sold about 100,500 copies (and that figure probably reflects only about 70 percent of actual sales.)  "What constitutes a disappointment for Coulter would be a mega-hit for most authors," points out Jeff Berovici, writing for Portfolio.

But for Coutler, those are indeed smaller figures than she is used to. With the book "moving steadily down the best-seller list," writes Berovici, "it looks certain that 'Guilty' will fall far short of matching her earlier results."

According to BookScan, Coulter's "Godless: The Church of Liberalism," (2006) sold 279,100 copies in hardcover while "Treason: Liberal Treachery from the Cold War to the War on Terror" ( 2003)  sold 396,600 hardcover copies and "Slander: Liberal Lies About the American Right" (2002) sold 333,100 copies, plus another 108,300 in paperback.
