Ken Livingstone is somewhere on the middle on this: we need campaigning from below and leadership which goes out on a limb.
Perhaps Maggie could inspire this.
"Margaret Thatcher took risks. It was because she had an ideology. She was always out on a limb. She never had a majority in Cabinet. But she shifted the whole of post-war politics away from a social democratic politics to a market driven one.
That was because she had guts. She was mad but she had guts. [laughter]
I wish ours were sane, but that they had guts too.
