Although post-communist party systems have shown signs of stabilisation in recent years, they are still susceptible to the emergence of new parties. Sikk (2012) and Sikk and Hanley (2014) have suggested that many of these challengers owe their success to a distinct winning formula, appealing to the public primarily on the basis of their ‘newness’ and antiestablishment credentials. However, to draw conclusions about the relative importance of newness in explaining the successes of these parties, it is necessary to understand the nature of their support among the electorate. Few empirical demand-side analyses of party support in the region explicitly address the newness thesis. This paper analyses support for Poland’s Palikot Movement, a party which rose to prominence in 2011 and for whom newness constituted a significant aspect of its electoral appeal. It shows that while the Palikot Movement attracted voters who disliked the other parties, support for the party was more clearly attributable to its distinct ideological profile rather than its claim to represent those dissatisfied with the actions of the political establishment.
