Political polarization, voting and democratic representativeness: Too much or too little?

This contribution evaluates the mediating role of different political contexts and levels of democratic consolidation on the effect of party system polarization on ideological vote and discusses how this relationship enhances democratic representativeness. The influence of party system polarization on ideological voting is analyzed in two areas: the voters' competence in identifying parties' ideological positions; and the voters’ tendency to vote for the most ideologically proximate party, which is one of the key features of the spatial theories of voting. Using data from the Comparative Study of Electoral Systems (CSES) from 1996 to 2019 and multilevel modelling techniques, the paper compares how those features vary across different types of countries, particularly older and newer democracies, and different regions of the world.
