Where party identification is in decay or in flux, alternative political identifications have gained centrality.

In this Element, the author develops a typology of post-partisan political identities: alternative ways in which rejection of or the absence of partisan politics are defining political identifiers or non-identifiers.

Based on original evidence collected through opinion polls in different Latin American countries, as well as applying an innovative measurement, the author shows the respective magnitudes and ideological composition of anti-partisans (individuals who hold negative partisanships: strong identities based on predispositions against a specific political party or movement), anti-establishment identifiers (individuals who hold many negative partisanships simultaneously), and apartisans (individuals who lack any positive or negative partisanships).

This Element demonstrates the usefulness of employing these categories in order to better understand different levels of party system institutionalization, party-building, and partisan polarization in the region.
