Columnists like Johann Hari can certainly dream that Blair and company will change the voting system, challenge the power of the press, and put Brownite issues at the heart of the manifesto. It is not going to happen. Tony Blair chose Alan Milburn to run the campaign and marginalised Gordon Brown precisely because he is deeply conservative on all the major issues facing the country.
No principled and progressive party would join the Tories in scapegoating immigrants. But New Labour is neither principled nor progressive. It is because Blair and Milburn pander to the reactionary politics of the right that many Labour supporters are considering tactical voting to reduce the chances of a massive Blair majority and even more unprincipled shifts to the right.
