One year into the Obama administration there is a bad craziness snaking through America: the Wingnuts are on the attack. They are the unhinged activists, professional partisans and paranoid conspiracy theorists on both the far right and far left of the political spectrum, whose hate and hyper-partisanship since Obama's inauguration threatens to mock the promise upon which he was elected. In ''Wingnuts'', journalist John Avlon travels to the outer-reaches of American politics to explain how far-left and far-right extremists came to dominate the nation's political dialogue. From the revolutionary-inspired ''Tea Party'' protests to the healthcare town hall 'hijackings', principled policy opposition to government spending has taken a sharp right turn into Crazytown. Not to mention Sarah Palin's rants about administration 'death panels', attacks like Obama-as-Hitler/Communist/Antichrist and actual death threats against elected leaders. For those with a vested interest in stirring the crazypot - like the hyper-partisan talk-show radio and cable news hosts - all of this has been good for business: hate is a cheap and easy recruiting tool.
