Michele Bachmann's book has a title: "Core of Conviction." The cover (plain white background, Bachmann in simple red blazer over a collarless white blouse) is now being listed on Amazon.com, in preparation for a Nov. 21 release date. Careful observers of Monday night's presidential debate in Florida will have noticed Bachmann's subtle promo-line-embedded-in-talking-point: "I know what to do," she said, "and I have the core of conviction to be able to make the changes..." The book, serving as the GOP contender's campaign autobiography, is being published by Sentinel, a conservative division of Penguin.
