The left-wing coalition broadly agrees on economic questions but is divided on cultural questions like criminal punishment and school discipline, where graduates are much more liberal than non-graduates. By contrast, the right is united by cultural conservatism but differs on economics, where graduates are much more firmly in favor of free markets. British politics increasingly consists of two blocs, but this chart suggests they’re defined by different dimensions. The left-wing bloc is defined by economics, and the right-wing bloc by culture. Strategically, each side gains from focusing on its defining dimension, as Ansell and The Economist’s Archie Hall point out. Talking about issues that split your voters is bound to make some of them unhappy.
