The roles and realities of party membership at the 2019 General Election

党员是政党的重要资源，特别是在选举期间。通过对六个政党的成员进行调查，我们探讨了他们在竞选期间为自己的政党做了什么，以及这种情况是否会随着时间的推移而发生变化，特别是随着新的竞选形式（通常是在线形式）取代（或至少补充）旧的做事方式。我们还了解了成员们对在这次选举中被证明特别有争议的事情的感受，因为政党不得不暂停人们的参选-即候选人的选择（和审查）。我们还研究了党员的人口统计特征和态度：随着时间的推移，他们有多大的变化和变化，以及他们所在政党的选民有多大的代表性（或不代表性）？最后，我们调查了政党之间是否有大量成员流动，特别是“留欧派”是否从保守党和工党转移到自由民主党等政党，以及以前可能属于英国独立党（也许支持英国脱欧党）的脱欧派是否已经转为保守党成员。

Members are a vital resource for political parties - particularly at election time. By surveying members of six political parties we explore just what they do for their parties during campaigns and whether that is changing over time, particularly as new forms (often online forms) of campaigning replace (or at least supplement) the old way of doing things. We also find out how members feel about something that has proved particularly controversial at this election owing to story-upon-story of parties having to suspend people from standing - namely the selection (and vetting) of candidates. And we look at the demographic characteristics and attitudes of party members: how much do they vary and change over time, and how representative (or unrepresentative) are members of their parties' voters? Finally, we investigate whether there has been much movement of members between parties, and in particular whether 'Remainers' have moved from the Tories and Labour to parties like the Lib Dems and whether Leavers who might previously have belonged to UKIP (and perhaps support the Brexit Party) have switched to membership of the Conservatives.
