Can David Miliband succeed?
Just look where he is coming from as a loyal Blairite. New Labour junked everything that Labour hitherto stood for, social equality, civil liberties and international law, in order to profit from and ingratiate itself with big business and win ephemeral support from Middle England. Electoral success became the only raison d'etre for this compromised and unprincipled party.
Today the Labour Party has the backing only of its core voters who have nowhere else to turn. David Miliband has nothing in common with those people and their problems.
The great shame is that David didn't learn anything from his famous and much respected father. But there again if he had he wouldn't have risen to the top of New Labour.
