YouGov have looked at where the Party’s votes came from compared to 2015 and produced a Sankey Diagram, which I think is really cool.
I am not sure it shows the first time voters; there should be a black segment on the left with the label “Didn’t Vote”. The original has overlays showing the swing from Tories to Labour and the loss of votes by the small parties. Labour’s challenge was to win votes from everywhere including those that didn’t vote. It actually did this, although not enough to win the election; those who thought it was too much for one election were right.
Swing!
This was written in August 2018 as I was reading “The Candidate” by Alex Nunns, and I have backdated it to nearer the time it would have been created.
