Tony wasn't elected by the people though he was elected by the Labour Party members who were also behind Gordon Brown. It's a mistake to think that. Our premiership is never elected by the people. Only in the sense that they are voted in by their constituents but if course Gordon was too like all MPs.
I've not read the book nor will I. I think Tony dud the right thing to take the party to the central ground in order to get in in the '90s. But times changed and New Labour didn't. Gordon was a much better man. He was no media darling but he was solid and cared passionately for Labour values. He was the best chancellor we may ever have but perhaps wasn't right for the premiership at that time. I always supported him though.
My impression of the snippets I've heard is that Tony remains arrogant and conceited and continues to measure the political climate by the '90s. Back then we needed to win votes from the Tories but we have only lost 1million voters to them this time. Instead we have lost 4 million to the Lib Dems. These are our disaffected voters from the left not the right.
