“…In the literature on the use of popular referendums to settle constitutional issues, an increasing number of studies has been devoted specifically to referendums on electoral systems, particularly in the wake of such votes taking place in New Zealand in 1992 -1993 (Levine and Roberts, 1994;Nagel, 1994;Vowles, 1995;Vowles and Lamare, 1996;Aimer and Miller, 2002) and in the UK in 2011 (Whiteley et al, 2012;Clarke et al, 2013;Curtice, 2013;Vowles, 2013). Whereas the conventional approach to electoral reform focuses on the rational interests and strategic interactions of political elites (Boix, 1999;Benoit, 2004;Colomer, 2005), instances of entrusting the decision to maintain or overhaul extant electoral rules to ordinary voters have prompted more scholars to examine factors that influence individual attitudes towards electoral systems.…”
