“…Cross-national research on advanced democracies has produced excellent work on new party formation and entry, their electoral, and parliamentary performance as well as government participation (see, for instance, Hug, 2001; Heinisch, 2003; Tavits, 2006; Bolin, 2007; Meguid, 2007; Deschouwer, 2008; McDonnell and Newell, 2011; Spoon, 2011; Akkerman and de Lange, 2012; Biezen and Rashkova, 2014). However, more fundamental questions about the survival of new parties are surprisingly rarely dealt with (but see on old democracies Collignon, 2018; Lowery et al , 2013; Rose and Mackie, 1988; on new democracies Bakke and Sitter, 2015; Deegan-Krause and Haughton, 2015; Cyr, 2016; Casal Bértoa and Spirova, 2017). Drivers of party death and survival shed light on the fundamental question of how we should theorize what political parties are.…”
