Former US vice-presidential candidate Sarah Palin stands next to the Liberty Bell in Philadelphia, Pennsylvania, during her 'One Nation' bus tour. The official aim of the tour seems to be "to educate and energise Americans about our nation's founding principles, in order to promote the Fundamental Restoration of America". However, most observers agree it is an attempt to drum up support for a run at the presidency in 2012. Photo: Jeff Fusco
