In a recent Political Bookworm item focusing on his book "The Virtues of Mendacity: On Lying in Politics," guest blogger Martin Jay noted that "truth-telling is not always the best policy in even the most democratic of political contexts." John Amato and David Neiwert get quite worked up over this notion, especially as it applies to the conservative right. In their book, "Over the Cliff: How Obama's Election Drove the American Right Insane," due out in June from PoliPoint Press, the authors explore the false stories they say are propagated by figureheads of the right such as Glenn Beck, Rush Limbaugh and Lou Dobbs. Here they identify 10 beliefs of the Tea Party movement that they say are provably untrue. Amato is founder of Crooks and Liars, a progressive weblog. Neiwert is editor of the weblog Orcinus.
