محدودیت وفاداری حزبی: چگونه همه پرسی در استقلال اسکاتلند هزینه کار

The 2015 General Election saw a collapse in Labour support in Scotland resulting in almost total annihilation in terms of Parliamentary seats north of the border. In this paper we show how the referendum on independence in Scotland in September 2014 precipitated this upheaval. Drawing on theories of attitudinal and behavioural inconsistency from social psychology, we reveal how Labour supporters who voted ‘Yes’ to independence subsequently became more favourably disposed towards Scottish National Party (SNP) and the policies that they advocated. A realignment of attitudes and voting among erstwhile Labour voters meant that those supporting independence were more likely to switch to the SNP after the referendum. We argue that the Scottish independence referendum had a profound re-aligning effect on party identification in Scotland, cementing the link between SNP voting and pro-independence attitudes.
