From a blogger called Simon:
I think this idea that Livingstone has a big 'personal vote' is dangerous, even though it's true, because it obscures the fact that he also appears to have developed a negative personal vote which might be stickier than Labour's national poll trajectory. So even in a situation where Labour has recovered (as is likely to be the case in 2012) If Livingstone stands again his sticky negative personal vote might to some extent cancel out his personal vote and lead to another defeat. If Livingstone and his coterie think that his vote will consistently run a specific number of points ahead of the Labour vote in all circumstances, they are mistaken.
Simon went to several of Saturday's sessions. He particularly liked the ones about transport and new media. Read the whole of his account here.
