Serbian party system is in the phase of reconfiguration which can be perceived as the outcome of domestic incentives (crisis of democratic transition and of democratic rule) and the international one (economic and migrant crisis). On one side, this reconfiguration includes emergence of predominant ruling party (Serbian Progressive Party, SNS) with strong leader and popular support; on the other side, the opposition camp has been atomized into number of smaller parties. Most of these parties are the new one (including the SNS) and founded after 2008 elections and creation of pro-EU consensus among relevant parties; post-2008 period has been characterized by the decline of almost all old parties, followed by emergence, partial success and fast decline of a large number of new actors. In this paper I am investigating if these new parties can be explained as the unexpected consequence of ideological and political stability after 2008 elections, tactical narrowing of the ideological space and cartelization of the party system. Analysis will focus at populist and anti-partisan ideas, their interplay and different ideological interpretation.
