But these problems also existed in 2015 and young voters didn't bother to turn out. Corbyn would have done better than Miliband with young voters anyway, but the difference between 2015 and 2017 was huge. Anyway I'm looking at some polls from before the Brexit (ugh crosstabs...) and apparently young people already trended Labour before Brexit but after Corbyn's election so you're probably right. And I agree that we probably shouldn't derail the thread anymore .
The main difference is than Milibrand didn't focus on these issues in 2015, unlike Corbyn.
