It lacks the killer soundbite to be repeated ad nauseam on the news. There is little that will spread beyond the relatively small numbers that will listen to the whole speech.
I agree, but that bit was a positive. It's because Corbyn's speech was written in a manner for consumption by people who already share his views. He's not persuasive. That's down to the structure of his speech:
Don’t be angry at the government ministers running down our schools and hospitals, they tell us, be angry instead at the disabled woman or the unemployed man.Corbyn's just spent his time speaking for his opponents which is obviously confusing. How can you make a soundbite out of that? He doesn't account for the fact that people think whilst you talk, so they hear "Don't blame X" and think to themselves "oh, okay" and then pick up the sentence somewhere further down the line.
He needs to get to the point - Don't blame X. Blame Tory Y because <reason>. Then he'd have a soundbite.
Also, notice in this example he blames "
government ministers" instead of Tory ones. Two years in and he hasn't changed his language to someone intending to form a government. People pick up on these things even if they don't process them in real time.
