Restructuring the policy space in England: The end of the Left–Right paradigm?

Abstract

Political scientists often talk about ‘ideological dimensions’ that aggregate related policy issues into a single latent construct. Applying factor analysis and Mokken Scale Analysis to opinion data generated from a Voting Advice Application deployed in England in the run-up to the European parliamentary elections, I show how individual issues may be aggregated into two principal dimensions: an economic dimension that separates Left and Right in terms of the economy and a cultural communitarian–cosmopolitan dimension. I also identify a third (libertarian–authoritarian) dimension, but this appears to aggregate very few issues. By positioning party supporters on a two-dimensional map defined by the two principal dimensions, I show that United Kingdom Independence Party supporters are situated very near the ‘communitarian’ pole of the cultural communitarian–cosmopolitan dimension. Finally, I show that overall, the communitarian–cosmopolitan dimension forms a rather more coherent scale than the Left–Right dimension and this tendency is even more marked among younger voters and voters with little interest in politics. Overall, this would appear to show that the notion of (economic) Left and Right is losing its salience in English politics.
