My broad impression so far is that Labour has been smart to have the launch in front of an appreciative, presumably hand-picked, audience. Brown is a confidence politician and the more the crowd is behind him the better he comes over.
That’s working out well – the only danger of this is if the media start commenting on it and this becomes the story.
Let’s see how all this gets reported.
As to the details – who cares? Elections are about personalities – not policies.
