Gwen Ifill, Moderator of Biden/Palin debate, pens Pro-Obama book???

Gwen Ifill, who is moderating Thursday's vice-presidential debate, is releasing a book on Barack Obama and other young black politicians who are "forging a bold new path to political power."

How can she possibly be objective? And why isn't an objective moderator in place? Same could be said for the liberal moderator of the McCain/Obama debate, Jim Lehrer.
