Nationalization of elections refers to a situation whereby parties compete across the statewide territory where they win equally sized vote shares. This chapter traces the development in the conceptualization and measurement of the nationalization of elections. Nationalization is often broken down into a distributional and temporal dimension and scholars assess the extent to which vote shares (static nationalization) and vote share swings (dynamic nationalization) are similar across the territory. The argument put forward in this chapter is that the inclusion of regional elections entails more than settling measurement issues as it allows us to study the linkages or spillovers between national and regional electoral arenas. This chapter claims that denationalization should be studied in a multilevel electoral context which involves studying dynamic and static nationalization for both parties and regions in both regional and national elections as well as examining the extent to which electoral dynamics spill-over back and forth between regional and national electoral arenas.
