Another day, another distraction. With the vice presidential debate one day away, the news that the moderator, Gwen Ifill, has a supposedly pro-Obama book in the works is creating an uproar.  In the editorial board meeting this morning we talked about the possible results: Might Ifill be tempted to go more easily on Sarah Palin? Could the development prompt the McCain campaign to ask for a postponement and a new moderator?  What do you think? Should Ifill drop out, or should the arrangements for Thursday night remain as they are? Click on the comments button, please, and tell us what you think.
