(CNN) - Controversy swirled over VP debate moderator Gwen Ifill one day before the vice presidential face-off between Sarah Palin and Joe Biden, after new scrutiny was drawn to her upcoming book about Barack Obama.
In stories published Wednesday, conservative commentators noted that "Breakthrough: Politics and Race in the Age of Obama" – first announced several months ago – is slated to be released around the inauguration of the next president in January 2009, less than four months from today.
"...as if we needed any further evidence of a jaw-dropping double standard, we have to contemplate the sheer impossibility that someone who wrote a positive biography of McCain being chosen to moderate a debate," wrote Jim Geraghty on the National Review's Web site Wednesday.
The book has not yet been released to critics or the general public. Ifill talked about the upcoming book in a Washington Post interview in August, before the terms of the debate were finalized. In her only pre-debate interview, the PBS journalist told the Post's Howard Kurtz, a CNN contributor, that her book would cover new black political leaders like Obama, Massachusetts Governor Deval Patrick and Newark Mayor Cory Booker.
