The Today Programme’s Jim Naughtie has been on the road in the USA with his Edirol (or perhaps a Marantz or a Sony) and a producer. His mission is to examine the culture war between God-fearing,  Sarah Palin adoring fans of the conservative insurgency known as the Tea Party movement, and Liberal supporters of President Barack Obama. His features depicting and exploring the antipathy  that now divides Americans between two incompatible visons of their own national dream make fantastic radio. In the first piece he talked to Tea Party activists in Kentucky and found them spitting blood, fire and brimstone about the grim obscenity of ‘big government’ and the imminent threat of SOCIALISM…In the second Jim reported from cosmopolitan, multicultural New York and met Obama supporting trade union activists preparing for their Labour Day parade..Of course you have already heard and discussed these pieces, because every student and future student in the Centre for Journalism knows that listening to Today is an absolute duty as well as a joy, but just on the off chance that anyone was in the shower at 07.30 on Monday and Tuesday morning…
