British politics and what we’ve learned after the 2017 general election

Last month’s general election delivered the latest in a series of political surprises, with the Conservatives falling short of a majority when many had anticipated they would win a landslide. On 21 June the Constitution Unit hosted a panel of election experts consisting of YouGov’s Joe Twyman and academics Justin Fisher, Jennifer Hudson, Philip Cowley and Alan Renwick to reflect on what happened. Fionnuala Ní Mhuilleoir reports.

Although we have become used to political upsets in recent years the outcome of the 8 June election nonetheless came as a surprise to many, including the Prime Minister, who saw her majority disappear when she had hoped to increase it substantially. How did this happen? How did the Conservatives manage to lose the massive lead they held at the start of the campaign, and Labour out-perform all expectations? How did the pollsters do after they had failed to call the 2015 election correctly? And what does the result mean for the government’s position in the new parliament, and for Brexit and beyond? These questions were all discussed at a Constitution Unit seminar held on 21 June, chaired by the Unit’s Director Professor Meg Russell. The panel included YouGov’s Joe Twyman, Professor Justin Fisher from Brunel University and Professor Philip Cowley from Queen Mary University of London. Dr Jennifer Hudson and Dr Alan Renwick from the Constitution Unit completed the line-up.

Joe Twyman

Joe Twyman opened the seminar with a brief post mortem on YouGov’s 2015 general election polling, which had predicted that the Conservatives would be the largest party in a hung parliament. The Conservatives went on to win 330 seats, securing a small but workable majority. YouGov subsequently identified three problems in the 2015 polling process: the samples used by YouGov and other polling companies to measure voting intention were not representative; figuring out whether people will turn out to vote is challenging; seat estimation across 650 constituencies is inherently very difficult.

Twyman then described how YouGov has responded to these issues. First, it has invested heavily in targeted recruitment, spending more than £100,000 in the last year to identify and recruit the types of people who were underrepresented in YouGov samples between 2010 and 2015, particularly those who were not interested in politics. Second, YouGov has updated how it analyses turnout. Thirdly, it has also developed a new seat estimation model.

This seat model, as is now well known, correctly predicted a hung parliament. In the run up to June 8 YouGov faced trenchant criticism, both from established commentators and on social media. Twyman reflected on Paul Krugman’s statement after the US election results that economists and commentators ‘truly didn’t understand the country we live in’. Through the efforts of YouGov, according to Twyman, we do now understand the country we live in a little better.

Justin Fisher

Justin Fisher began his contribution by drawing the audience’s attention to how important lead time ahead of an election is for party campaigns. The national and constituency campaigns have merged, with national campaigns now supporting the constituency effort. Lead time gives parties more time to plan targeting, information distribution, spending and fundraising. In a normal election campaign the critical period is the six-to-nine months before the poll.

The snap election left no opportunity for such advance campaigning. One implication is that this is likely to have been a much less expensive campaign than usual. Another is a shift in emphasis in campaigning techniques from direct mail (which requires lead time) to face-to-face campaigning and e-campaigning, which require much less preparation time. Fisher stressed that the evidence needed to confirm these expectations is still being collected.

Though the 2017 election may have accelerated the shift to e-campaigning, Fisher argued that campaigning techniques were partly heading that direction regardless. He also warned of what he called e-campaigning myths. He debunked the myth that micro-targeting of voters had only just been invented: parties have gathered data from phone calls and indirect mail for years. E-campaigning, therefore, represents evolution rather than a revolution. A further myth is the claim that because parties are using e-campaigning it must be effective. In 2015, research found it to be electorally effective, but less so than face-to-face campaigning. This has yet to be examined for the 2017 election.

The campaign and general election in review

David-Ireland

This year’s general election result took almost everyone by surprise, including the pollsters, forecasters and other experts. On 3 June, Joe Twyman, Dr Ben Lauderdale, Dr Rosie Campbell, Professor Justin Fisher and Professor Matt Goodwin took part in a roundtable to discuss where the predictions went wrong and lessons for 2020. David Ireland offers an overview of the event.

The exit poll that came out at 10pm on 7 May took almost everyone by surprise. Over the course of Friday morning, the scale of the Conservative majority revealed itself, showing that even the exit poll had underestimated the Conservative support. What happened? How did the polls get it so wrong and what are the lessons for 2020? This blog highlights the key issues from a recent roundtable on GE2015 hosted by UCL’s Department of Political Science and the Constitution Unit and chaired by Dr Jennifer Hudson. 

Joe Twyman, Head of Political and Social Research, YouGov

As one of many pollsters who had long predicted a hung parliament, Joe acknowledged YouGov didn’t get it right this time. He also, rather humorously, showed the range of Twitter abuse directed at him as a result.

Voting intention remained tightly balanced in the months leading up to the election, but YouGov’s polling revealed that the ‘fundamentals’ may not have been given enough weight in predicting vote share.Importantly, no party had ever come from behind on the economy and leadership to won an election before, and this election was not to be the first. The economy remained the single most important issue, and here, the Conservatives were significantly ahead. Similarly, Miliband never got close to Cameron on party leader ratings.  Continue reading
