Ever since she changed her political slant from right to left (many people head the other way), commentator and columnist Arianna Huffington has been ever more productive. Now, fresh off her attack on American corporate greed in Pigs at the Trough, she has decided to take on the current political standoff head-on. Her new book is called Fanatics and Fools, and in it she castigates both the Republican conservatives leading the republic down what she sees as devious paths and the Democrats who are spinelessly letting them get away with it. Miramax editor Susan Mercandetti signed for world rights from agent Arthur Pine and aims to publish next spring. The author's last book was with Crown, which recently added a conservative imprint that was probably not to her liking.
