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

党员是政党的重要资源，尤其是在选举期间。通过调查六个政党的成员，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改变，特别是当新的竞选形式（通常是在线形式）取代（或至少补充）旧的竞选方式时。我们也发现了议员们对选举中特别有争议的事情的看法，因为一个又一个的政党不得不暂停人们的参选资格，即候选人的选择（和审查）。我们观察党员的人口特征和态度：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很多成员的流动，特别是“留欧派”是否已经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（可能支持英国退欧党）的脱欧派是否已经转变为保守党的成员。

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.
