In her game-changing convention speech, Sarah Palin took a swipe at Obama for having been nothing more in his life than a ‘community organiser’. This prompted the Obama campaign to issue a pained defence of community organisation as a way of promoting social change ‘from the bottom up’. The impression is that community organising is a worthy if woolly and ultimately ineffectual grassroots activity. This is to miss something of the greatest importance: that in the world of Barack Obama, community organisers are a key strategy in a different game altogether; and the name of that game is revolutionary Marxism.
