Poll: Palin's favorables up four points since October, now 44/47

While releasing a best-selling autobiography may have had a modest positive effect on views of her, it did not register quite the same impact as former first lady Hillary Clinton’s book release appeared to in June 2003. Prior to the publication of Clinton’s memoir “Living History,” 45% of Americans viewed her favorably and 46% unfavorably. Those ratings shifted to 53% favorable/43% unfavorable when the book was released, and remained above 50% for the next three-plus years.
