The political leadership lies at the origin of most transformations in democracies today, e.g. policies, institutional gridlocks, radicalization. An extensive body of literature argues that political leaders are key players in politics in general and in their political parties in particular: the recruitment of political personnel, setting the policy agenda, the coordination of party activities and the public image of the party. So far, research on political leadership focused mainly on established democracies and well-known leaders.
