There was an interesting comment from John Curtice about election turnout in general.
It has always surprised me how low election turnout is - and how when you look at age bands, it's much lower in younger age bands than in older age bands.
Enthusing people, giving them something to vote for, especially the younger generation, and making sure they can vote easily (Voter ID - looking at you), ensuring they are on the electoral register - so that constituencies are fair - basically engaging people is so important.
The Brexit referendum got a turnout of 72%.
The 2019 election turnout was 67.3%
That is a LOT of registered voters not voting - and we don't even know about the unregistered voters
