George W Bush's presidency has, like the Thatcher era in the UK created a new breed of angry, left-wing US comics such as Patton Oswald and Eugene Mirman. However, there's an equally angry right-wing stand-up movement and a new Christian comic scene. Stephen Armstrong explores the battle for the laughs and minds of America and talks to working comedians, including Brad Stine, who tours churches; Evan Sayet, who tours and runs a Right to Laugh night in LA; and Julia Gorin, who is on the bill for a New York comedy night for both Democrats and Republicans.
