Yeah I did see similarities. In that respect, though, it shows how much the left was beaten, that Corbyn ended up the torch bearer. Benn was a great orator, and a great mind. Of the current lot, McDonnell was certainly better at the rhetoric and firebrand nature, but prone to the odd gaff and stupid moment. Corbyn to be leader just didn't end up with the same passion in it as you'd have maybe expected / hoped for the great left vision.
But that article is interesting, about waiting for the appropriate time, about delivering a great speach, changing the direction of a movement through force of conviction and personality. Kinnock is an interesting politician really because, at his best, he could move people, he could persuade people to follow, he had fire... but somehow was never quite seen as a PM in waiting.
