<p>Literature on party nationalization suggests that political parties in highly nationalized systems tend to concentrate control over candidate selection to preserve a unified national image. However, nationalized parties may also delegate selection to regional leaders or broader selectorates to leverage local knowledge or enhance legitimacy. Despite these contrasting expectations, empirical evidence remains scarce. This research note aims to provide empirical evidence on nationalized parties’ candidate selection methods. Using data from the Varieties of Party Identity and Organization (V-Party) Project and the Constituency-Level Elections Archive (CLEA), this note shows evidence that nationalized parties more often rely on delegated procedures, involving local actors or inclusive selectorates. These results challenge the assumption that party nationalization necessarily leads to centralized or exclusive control and instead point to a pattern of power-sharing in candidate selection.</p>
