You won’t hear the argument that the Greens won through grassroots organising because the received wisdom in Westminster is that it doesn’t work. Politicians in most major parties see the ‘ground game’ as a nice-to-have – a bit of democratic theatre to keep the membership busy while the real work happens on television screens and in the columns of tabloid newspapers. But this view belongs to a political era that is now dead – one in which voters still felt some baseline trust in politicians and the media. Now, that trust is much harder to come by. And the only way to win it back is by listening.
