The present paper explores the issue of political polarization on social media. It addresses two main questions: 1) Whether the intensity of political partisanship on SNS varies significantly in different countries depending on the electoral rules; 2) what electoral rules are associated with higher levels of polarization on SNS. To answer these questions audience duplication approach is applied to the data on the followers of the official Twitter accounts of political parties of 16 democratic countries. Based on the topology of the audience duplication graphs, the political Twitterspheres of the countries are classified into five categories: perfectly integrated, integrated, mixed, polarized and perfectly polarized. The analysis demonstrates that levels of political polarization differ based on the electoral rules and party systems. Polarization is the highest in two-party systems with plurality electoral rules and the lowest in multi-party systems with proportional voting.
