His followers are voting for the leader they like, not one that can win electionsby Peter Kellner / August 12, 2015 / Leave a comment
Opinion polls often produce messy, even contradictory, results. That’s because public opinion is often messy and contradictory. Sometimes, however, poll findings tell us something with great clarity. YouGov’s latest survey of Labour’s leadership election is such a poll: it proves beyond doubt a proposition recently advanced by David Runciman, one of Britain’s best political scientists, in the London Review of Books.
Runciman distinguished between “instrumental” and “expressive” choices. He wrote: “If voting is instrumental then it’s presumed that voters are primarily motivated by the results they hope to achieve: leaders and parties who can deliver real benefits. If it’s expressive then voters are more interested in signalling who they are and what they value.”
Runciman postulated that Corbyn is attracting “expressive” support: people with a vote in the leadership election like him and identify with him, whereas supporters of his rivals attract “instrumental” support from people whose main concern is to pick a leader who can take Labour back into government.
Runciman is right. Forget the distraction about entryism by far left groups; Corbyn is winning because most of Labour’s selectorate are deciding their vote on expressive rather than instrumental grounds. We asked 1,411 people with a vote in the leadership election to assess the personal qualities of each of the four candidates, asking first about positive qualities and then about negative ones (see table at the bottom).
