Politics isn’t really about personalities. They’re just the puppet show. And politics isn’t really about ideas either, or not in the way some people seem to think. It’s about alliances. It’s about putting together coalitions of different classes or interest groups. Each group has its own ideas, its own story it tells itself, and the trick is to find some overarching idea or story which connects with enough of these different stories to allow a variety of groups to buy into it.
Historically in Britain, the Labour Party managed to be the titular party of the industrial working class but also the party of an important section of the professional middle classes, the delicado class as I have called them*. (The Democratic Party in America managed a similar alliance in the twentieth century, though it has presided over many different groupings in its two hundred year history). This is not to say that the delicados and the industrial working class see the world in the same way -they obviously don’t- or that they have the same priorities or the same values, but they had enough common interests and common enemies to make it possible to construct a story that both could buy into. It was a story, I suppose, about using the state to make society fairer, and to reduce the power of inherited privilege, which had an appeal to both these groups, though for different reasons.
I would say the last flowering of this alliance in the case of the Labour Party was the Blair era. Blair was able to draw in a substantial number of new middle class voters who had previously voted Tory, while still retaining the traditional industrial working class vote. (My feeling is that he didn’t actually earn the latter, but was able to benefit from historical loyalties, which had yet to fade.)
I think recent electoral politics in Britain have shown that this old alliance no longer holds. In Scotland, Labour has been displaced as the dominant party by the SNP (I don’t know enough about Scotland to understand the alliance which this represents, but clearly it has drawn support from both of Labour’s traditional constituencies). In England, the Brexit vote and the recent election show that Labour can no longer take for granted the support of the voters it was originally set up to represent. The Conservatives have managed to find a story -and like the SNP’s, it is a story about nationhood and independence- which suits many of these voters better. A new alliance is forming between the non-delicado section of the middle class, and the old working class.
If we see politics as just being about ideas, and we are convinced that our idea is simply ‘right’ (as opposed to simply being the story our particular grouping prefers), we don’t respond effectively to the loss of an ally, because we conclude that our former ally is mistaken, or misled, or no longer worthy of us. And so we keep plugging away at the same idea, waiting for others to see the error of their ways, when the fact is that our story simply doesn’t appeal to enough people. We need a new idea.
It seems to me that the political ‘right’ (I actually hate the lazy simplification that divides politics into ‘the Left’ and ‘the Right’ but I’ll use it here for brevity), understands this at the moment better than the political ‘left’. You need to find out what different sections of the population want, not just in a practical sense (jobs, public services etc), important though that is, but in the sense of symbols and stories, and you have to deliver enough of what people want to make them feel like joining, or remaining part of, your alliance.
