"Whereas Tony Blair or Gordon Brown facing an election would have tried to give a proper account of the challenges facing Britain – in terms of globalisation, technology, migration – Miliband burbled on like a student leader running a rent strike. I might not have bought what Blair or Brown prescribed, but at their best they told a proper story. They treated the challenges seriously.
Viewed from that perspective, the dire amateurishness of the Miliband approach is actually rather insulting. The man who seeks to be Prime Minister thinks that what he is offering is good enough when it is plainly not."
