Jeremy Cliffe of The Economist asks if our real political divide is between those who feel comfortable in liberal, diverse, urban Britain and those who do not - the cosmopolitans vs the rest. He argues that the success of UKIP is one sign of this division. At one end are the cosmopolitans - comfortable in diverse Britain, urban and socially liberal. At the other end are the non-cosmopolitans, who tend to be older, white, and socially conservative, This new divide poses a serious problem for the established political parties. How can they appeal to one side without alienating the other? And what role does the traditional left-right split play?
