Yes, Prime Minister: The key to forecasting British elections

We use our “PM and Pendulum” Model to forecast the outcome of the 2010 General election. The vote function of the model, aside from a cyclical dynamic, relies on approval of the prime minister as the sole predictor. We find that PM Approval predicts the vote (and vote intention between elections) more accurately than does Government Approval. Turning to the forecasting of seats, we examine the accuracy of the autoregressive model of the vote-seat translation against the uniform-swing model, which is widely used by pollsters and the media. Testing the alternatives on election data since 1910, our autoregressive vote-seat translation model proves superior to the uniform-swing model.     

The Economic Consequences of a Hung Parliament: Lessons from February 1974

The British general election on 10 May 2010 delivered Britain's first hung Parliament since February 1974, and in the run‐up, the Conservative party made much of the economic difficulties Britain faced in the second half of the 1970s in order to try and convince voters that anything other than a Tory vote would risk exposing the nation to the discipline of financial markets. The question of how well equipped an exceptional kind of British government is to deal with exceptional economic circumstances is therefore of paramount importance. This paper argues that the Conservative party made too much of the impact of the 1974 hung Parliament in precipitating subsequent economic crisis and suggests that as such, there is no reason to assume that the Conservative–Liberal coalition government is ill‐equipped to manage British economic affairs in difficult circumstances.     

Nowcasting V. polling: The 2010 UK election trials

This paper first offers a final forecast for the May 2010 UK general election based on our “two-step model” [Nadeau, R., Lewis-Beck, M.S., Bélanger, É., 2009. Election forecasting in the United Kingdom: a two-step model. Journal of Elections, Public Opinion and Parties 19, 333-358.]. That model is then used to explore a new technique, “nowcasting.” We examine our model “nowcasts,” comparing it to the classic forecasting strategy of the vote intention poll, across the contemporary election period, 2005-2010. As is shown, nowcasting offers forecasting advantages that simple polling does not. Most notably, the nowcast provides variation that appears much more subject to substantive explanation of the electoral cycle, and it provides predictions with a three-month lead.     

‘Get Brexit Done’: The New Political Divides of England and Wales at the 2019 Election

This article analyses the successful Conservative election campaign of 2019 and how it took advantage of a fractured political and economic landscape. It reviews the unique circumstances around the 2019 election and the ‘surprising death’ of a no-deal Brexit. We then analyse the divergent political communication strategies in the 2017 and 2019 Conservative campaigns showing how the latter was much more coherent and politically unorthodox. Drawing on socioeconomic, demographic and British Election Study data, we argue that Boris Johnson’s messaging was carefully tailored towards the demands of voters in the ‘red wall’ seats. Conservative success was built around an appeal to voters in these economically depressed ‘geographies of discontent’. But while tremendously successful, the coalition this created is potentially fragile. An unconventional, ‘leftish’ Conservative campaign built a new, diverse bloc of voters. It includes a number of left-wingers expecting change alongside traditional Conservative supporters, and will be hard to keep together given the economic turbulence ahead.     

Economic globalisation,the perceived room to manoeuvre of national governments,and electoral participation: Evidence from the 2001 British General Election

Recent macro-level research argues that economic globalisation negatively affects electoral turnout by constraining the leeway of national governments and thereby rendering elections less meaningful to voters. This article analyses the link between perceptions of the national government's room to manoeuvre and turnout on the individual level. Drawing on the 2001 British General Election, it is shown that citizens who believe that economic globalisation leaves the national government with less influence on the economy are less likely to report to have voted. Further findings also support the proposed theoretical model according to which room to manoeuvre perceptions affect turnout via views on the importance of elections and matter specifically for citizens that tend towards the left side of the left-right scale.     

Citizen forecasting: Can UK voters see the future?

The leading approaches to election forecasting have been statistical models, prediction markets, or vote intention polls. This paper explores a different, little used approach - citizen forecasting - a method never yet tried for the case of the United Kingdom. Citizen forecasting simply asks voters in a scientific pre-election survey who they think will win. This aggregated (averaged) result is then assessed for its accuracy in forecasting the overall election outcome. This assessment is carried out on UK general elections from 1951 to 2005, and then applied to 2010. We find, among other things, that generally speaking the majority of the electorate can foretell the winner in advance.     

Aggregate level forecasting of the 2010 general election in Britain: The Seats-Votes model

The Seats-Votes model forecasts party seat shares in the House of Commons using data from general elections and opinion polls between 1945 and 2009. The model is built on a generalisation of the cube rule which provided a fairly accurate method of translating votes into seats when Britain was effectively a two party system prior to the 1970s. It combines past information on seat shares in the current Parliament with voting intention data six months prior to the general election to forecast seat shares. Applied to the task of forecasting the outcome of a general election in early May of 2010, it predicts a hung Parliament, with the Conservatives as the largest party. The relatively small sample used to estimate the model means that predictions about the size of the parties in Parliament are quite tentative, though predictions about the likelihood of a hung Parliament are more certain.     

Forecasting the 2010 general election using aggregate local election data

The paper presents a revised method for estimating national vote shares using aggregate data from local government by-elections. The model was originally developed to forecast the annual outcome of local elections but was adapted in time to provide an accurate forecast of Labour’s landslide victory at the 1997 general election. However, over the past decade the changing pattern of party competition which has seen parties becoming more selective about which elections to contest has led to more elections being excluded from the modelling because they failed to meet the exacting criteria that all three major parties, Conservative, Labour and Liberal Democrats, had contested both the by-election and the previous main election, normally held in May. Relaxing these criteria, although increasing the number of available cases would adversely affect the forecast, over- or under-estimating party votes. Instead, the revised method overcomes the problem of differential competition by estimating vote shares for parties that contest one but not both elections. A further innovation is the calculation of a weighted moving quarterly average which takes account of the number of days elapsed between the by-election date and the date of forecast. Using the new method we provide estimates for likely party shares for the 2010 general election.     

Do local elections predict the outcome of the next general election? Forecasting British general elections from local election national vote share estimates

This article outlines a method for forecasting British general elections from national level vote shares at local elections. Although local elections are notionally ‘local’, the evidence suggests that they at least partly mirror national electoral fortunes. A simple general election vote share on local election vote share regression model that accounts for partisan differences and incumbency effects fits past data with reasonable accuracy. Based on the results of the 2013 and 2014 local elections, the model forecast a 56% probability of hung parliament, with a 78% probability of the Conservatives receiving the largest share of the vote.     

Victory without power: The Pm-Pendulum forecast

The “PM and Pendulum” model was adjusted for the 2015 General Election to take account of the Liberal-Democratic participation in government and the SNP surge. So adjusted, the model predicts a Tory vote victory by 3.4 percent over Labour. The seat forecast puts the Tories ahead with 287 seats to 263 for Labour, with 41 for the SNP. Thus another Hung Parliament! Ex-post estimates show that without the Lib-Dem adjustments the model would have predicted a Conservative majority.     

Brexit,the 2019 General Election and the Realignment of British Politics

The outcome of the 2019 general election—a resounding Conservative majority and an unprecedented defeat for Labour—delivered a decisive electoral verdict for the first time in recent years following a period where British politics has been characterised by instability and indecision. In this article, we draw on aggregate-level data to conduct an initial exploration of the vote. What was the impact of Brexit on the 2019 general election result? How far has Brexit reshaped electoral politics? Was 2019 a ‘realignment election’? And, if so, what are the implications? With a focus on England and Wales we show that, although the Conservatives made gains deep into Labour’s working class heartlands, these gains have been a long time coming, reflected in Labour’s weakening relationship with working class Britain. As such, 2019 is not a critical election but a continuation of longer-term trends of dealignment and realignment in British politics.     

The 2017 General Election,Brexit and the Return to Two‐Party Politics: An Aggregate‐Level Analysis of the Result

The outcome of the 2017 general election—a hung parliament—defied most predictions. In this article, we draw on aggregate‐level data to conduct an initial exploration of the vote. What was the impact of Brexit on the 2017 general election result? What difference did the collapse of UKIP make? And what was the relative importance of factors such as turnout, education, age and ethnic diversity on support for the two main parties? First, we find that turnout was generally higher in more pro‐remain areas, and places with high concentrations of young people, ethnic minorities and university graduates. Second, we find that the Conservatives made gains in the sort of places that had previously backed Brexit and previously voted for UKIP . But, third, we find that the gains the Conservatives made from the electoral decline of UKIP were offset by losses in the sort of places that had previously supported the Conservatives, particularly areas in southern England with larger numbers of graduates. The implication of these findings is that while a Brexit effect contributed to a ‘realignment on the right’, with the Conservative strategy appealing to people in places that had previously voted for UKIP , this strategy was not without an electoral cost, and appears to have hurt the party in more middle class areas.     

Squeezed Out? The Liberal Democrats and the 2019 General Election

The 2019 general election was a crushing disappointment for the Liberal Democrats, as Jo Swinson lost her East Dunbartonshire seat to the SNP and the party’s anti-Brexit stance failed to deliver gains from the Conservatives. Although the Liberal Democrats’ poor performance can partly be blamed on a misfiring campaign strategy, it also reflected the structural difficulties which the party faces in an increasingly polarised political environment. The polarisation of public opinion along multiple axes over the last decade—over austerity, Brexit, and attitudes to Jeremy Corbyn—has fractured the broad coalition of support which the Liberal Democrats assembled during the 1990s and 2000s. Analysis of the 2019 results suggest that the party has made some progress towards developing a new core vote, particularly among suburban Remainers in south east England, but it is not clear whether this will be large or robust enough to have a significant impact on the future of British politics.

“Wisdom of crowds”? A decentralised election forecasting model that uses citizens’ local expectations

Many studies report the “wonders of aggregation” and that groups (often) yield better decisions than individuals. Can this “wisdom of crowds”-effect be used to forecast elections? Forecasting models in first-past-the-post systems need to translate vote shares into seat shares by some formula; however, the seat–vote ratio alters from election to election. To circumvent this problem, this paper proposes citizen forecasting, which aggregates citizens’ local expectations to directly forecast constituencies. Using data from the 2010 British Election Study, this paper finds (1) that groups are better forecasters than individuals, (2) that citizen forecasting correctly predicts a hung parliament, and (3) that marginality and group size are important predictors for “getting it right”.
