Dr. Umansky & Prof. Sened published an article examining how challenger parties enter the political area and the effect of this entry by looking at the Italian 5 Star Movement (Movimento 5 Stelle – M5S).
“We explain the M5S’s entry strategy in 2013 using the spatial approach to party competition and employing expert survey data collected for each national election between 2008 and 2018. These data allow us to analyze the changing spatial configuration of Italian politics due to the increasing salience of pro/anti-EU and pro/anti-immigration dimensions. We then apply the theoretical notion of the uncovered set (UCS) to trace how the M5S’s entry reshaped the overall space of party competition, causing a realignment of existing parties. This work contributes to the ongoing debate on the electoral success of challenger parties and the emerging cleavages and polarization of party systems in Western European countries.”
