3.1.2.2b - Voting Behaviour and Election Case Studies

Scope: This lesson covers voting behaviour models and factors, then applies them to three AQA-required UK general election case studies: 1983, 1997 and 2019. Electoral-system effects are included only where they help explain voting behaviour and election outcomes.

Models Of Voting Behaviour

Voting behaviour means the patterns and explanations of how people vote. AQA does not expect one magic explanation for every election. Strong answers show how long-term social patterns, short-term campaign factors and the electoral system interact.

Voting behaviour

The study of why individuals and groups vote as they do, including social background, party attachment, issues, leadership, media influence and campaign effects.

Class alignment

A pattern where voters from particular social classes strongly and consistently support particular parties, for example manual working-class voters tending to support Labour and middle-class voters tending to support the Conservatives.

Class dealignment

A weakening of the link between social class and party choice, so class becomes a less reliable predictor of voting behaviour.

The main models are:

ModelCore ideaExample of exam use
Sociological modelPeople are influenced by social groups such as class, age, education, region, ethnicity, gender, religion and housing tenure.Explaining why age and education were strong predictors in 2019.
Party identificationVoters have a long-term psychological attachment to a party, often shaped by family, class and community.Explaining why some "safe" Labour areas stayed Labour for decades before 2019.
Issue or proximity votingVoters choose the party closest to them on a salient issue.Brexit made party choice in 2019 strongly linked to Leave/Remain identity.
Valence votingVoters choose the party they think is most competent on goals almost everyone shares, such as economic management or public services.Labour's 1997 campaign tried to look competent and moderate enough to govern.
Rational-choice votingVoters weigh costs and benefits and choose the party that seems best for their interests.Homeowners, public-sector workers or pensioners may respond differently to tax, welfare or public-service pledges.
Leadership and campaign effectsLeaders, manifestos, media framing and campaign mistakes can shift, reinforce or demobilise voters.Johnson's 2019 campaign message was clearer than Labour's Brexit position.

A common AQA mistake is to treat these as rivals where only one can be true. In practice, they overlap. A voter may be working class, pro-Leave, hostile to one leader and influenced by a local campaign at the same time. Your job is to decide which factor carried most weight in a particular election.

Data And Factors

Election results tell us what happened. Voting-behaviour data helps explain who voted in different ways and why. For UK general elections, useful national sources include official result data from the House of Commons Library or Electoral Commission, polling aggregates from Ipsos, and survey analysis from the British Election Study.

Manifesto

A party's published programme of policies and pledges for an election.

Campaign

The organised attempt by parties, candidates and supporters to persuade voters during an election period, using speeches, advertising, visits, debates, media appearances, digital material and local canvassing.

Use the factors below as a checklist, not as a script.

FactorWhat to look forWhy it matters
Social classWhether AB, C1, C2 and DE groups split strongly by party.Shows class alignment, class dealignment or realignment.
Age and educationWhether younger/older voters or graduates/non-graduates divide sharply.By 2019 these were often stronger predictors than old class categories.
Region and nationScotland, Wales, London, the South, the Midlands and the North can behave differently.Explains why national vote share can hide different local contests.
Ethnicity and religionMinority groups may show distinctive voting patterns.Useful when supported by survey data, but avoid assuming all minority voters behave the same.
Gender and tenureMen/women, homeowners, private renters and social renters can differ.Links material interests to party policy and turnout.
MediaNewspaper support, broadcast framing and social media can reinforce or shift perceptions.Media matters, but causation is hard to prove. Correlation is not enough.
Manifestos and policiesClear, popular or risky pledges can shape the choice voters think they face.Voters may respond to both policy content and how opponents frame it.
LeadershipLeaders affect competence, trust, values and party image.Especially important in presidential-style campaigns under FPTP.

Two terms help with change over time:

  • Partisan dealignment: voters become less loyal to a party, so they are more open to switching.
  • Electoral volatility: more voters change party choice between elections, making outcomes less predictable.

1983: Pre-1997 Election

The 1983 general election is a useful pre-1997 case study because it shows leadership, manifesto positioning, national context and FPTP effects all working together.

Party or groupVote shareSeats wonMain point
Conservative42.4%397A large parliamentary majority from a vote share below 50%.
Labour27.6%209Labour remained second in seats despite a sharp vote-share fall.
SDP-Liberal Alliance25.4%23A near-Labour vote share translated into very few seats.

Political context. Margaret Thatcher's first Conservative government had faced recession and high unemployment, but by 1983 the government campaigned on economic recovery, lower inflation, trade-union reform, home ownership and national resolve after the Falklands War. The Conservative message framed continuity as strength and Labour's alternative as risky.

Manifestos and policies. Labour's 1983 manifesto was widely attacked as too left-wing for the median voter, especially on defence, public ownership, spending and Europe. Its commitments included unilateral nuclear disarmament and withdrawal from the European Economic Community. For AQA, the key point is not just the list of policies: it is that opponents turned the manifesto into a valence problem. Many voters were encouraged to ask whether Labour looked competent and safe enough to govern.

Leadership and campaign. Thatcher projected decisiveness and patriotic authority, helped by the Falklands context. Michael Foot was respected by many within Labour but struggled to look like a modern prime-ministerial alternative to enough voters. The SDP-Liberal Alliance, led by figures including Roy Jenkins and David Steel, offered a moderate anti-Conservative alternative, splitting the opposition vote.

Voting behaviour. Older and middle-class voters leaned strongly Conservative. Ipsos long-run data also shows the Alliance taking substantial support among middle-class voters, which damaged Labour's ability to present itself as the only alternative government. Class still mattered, but 1983 also shows that leadership, policy reputation and opposition fragmentation could disrupt simple class voting.

Electoral-system effect. 1983 is excellent for showing how FPTP can reward geographically concentrated support. The Alliance won just over a quarter of the vote but only 23 seats because its support was spread thinly. Labour won only slightly more votes than the Alliance but many more seats because its support was more geographically concentrated.

1997: Required Election

The 1997 general election is compulsory for AQA. It is a landslide case study, but it should not be taught as "Blair was popular, so Labour won". The better explanation is a combination of party repositioning, Conservative weakness, leadership contrast, media context and class dealignment.

PartyVote shareSeats wonMain point
Labour43.2%418Landslide majority and broad social reach.
Conservative30.7%165Heavy defeat after 18 years in government.
Liberal Democrat16.8%46More seats from anti-Conservative tactical and local voting.

Political context. The Conservatives had governed since 1979. By 1997 they were weakened by Black Wednesday in 1992, divisions over Europe, "sleaze" allegations and voter fatigue. Labour did not simply wait for the government to collapse; it repositioned itself as New Labour under Tony Blair.

Manifestos and policies. Labour's manifesto and pledge-card strategy were designed to reassure floating voters. Labour accepted much of the market economy, emphasised education and the NHS, promised constitutional reforms such as devolution, and avoided looking like a return to old Labour tax-and-spend politics. This was a valence strategy: Labour wanted to win voters who wanted change but also wanted competence.

Leadership and campaign. Blair offered youth, discipline and modernisation. John Major was personally seen by some voters as decent, but his party looked divided and exhausted. Labour's campaign was tightly managed, with simple messages, professional media handling and a strong focus on competence.

Media. The Sun's switch to Blair's Labour was symbolically important because the paper had backed the Conservatives for many years. Ipsos data found Sun readers in 1997 leaned Labour by 52% to 30% Conservative. However, media influence should be handled carefully. Oxford research suggests the endorsement was associated with extra Labour support among readers, but not enough to change the overall 1997 result. In an essay, the strongest claim is that media helped reinforce Labour's credibility and Conservative decline, not that it single-handedly caused the landslide.

Voting behaviour. 1997 is a classic class-dealignment example. Labour kept strong support among working-class voters but also became competitive among middle-class voters. Ipsos data shows the Conservatives still ahead among ABC1 voters overall, but by a much narrower margin than in earlier Conservative victories. Labour's broad coalition made the landslide possible.

Policy consequences. Elections influence policy and policy making. Labour's 1997 victory gave Blair a large mandate for constitutional reform, including devolution for Scotland and Wales, House of Lords reform, and rights reform. That does not mean every policy was caused by the election alone, but the scale of the majority made implementation much easier.

2019: Post-1997 Election

The 2019 general election is the post-1997 case study for this lesson. It is best understood as a Brexit election, but not only a Brexit election. It also shows leadership effects, age and education divides, class realignment and campaign clarity.

PartyVote shareSeats wonMain point
Conservative43.6%365Clear majority and major gains in Leave-leaning Labour areas.
Labour32.1%202Worst Labour seat total since 1935.
SNP3.9% UK-wide48Dominant in Scotland, showing regional/national variation.
Liberal Democrat11.6%11More votes did not translate into many seats under FPTP.

Brexit as an issue vote. The Conservative campaign made Brexit simple: pass Boris Johnson's withdrawal agreement and end the parliamentary deadlock. Ipsos estimated that Conservatives won most Leave voters, while Remain voters were split between Labour, Liberal Democrats, SNP, Greens and others. The British Election Study concluded that Brexit identities continued to structure electoral choices in 2019, though it warned that it was too early to call this a permanent realignment.

Age, education and class. 2019 shows why class alone is no longer enough. Ipsos estimated that Labour led very strongly among 18-24 voters, while Conservatives led heavily among voters aged 65 and over. Conservatives were ahead among voters with no qualifications, while graduates were more divided. Social class was less predictive than in older elections: Conservatives led among AB, C1 and C2 voters and were close to Labour among DE voters.

Leadership and campaign. Johnson offered a clear leadership message around Brexit and a promise to "level up" left-behind areas. Corbyn mobilised enthusiastic supporters but had weak ratings with many voters. Labour's Brexit position, involving renegotiation followed by a referendum, was more complex and harder to communicate. The Liberal Democrats' anti-Brexit message was clear, but their support was inefficiently spread and their leader Jo Swinson lost her seat.

Manifestos and policies. The Conservative manifesto mixed Brexit clarity with cautious tax pledges, NHS spending, policing, infrastructure and levelling-up language. Labour's manifesto was ambitious, with major public ownership and spending commitments, but opponents framed it as unrealistic. This is a good example of manifesto effects being both substantive and reputational: voters judge not only whether they like a policy, but whether the party looks able to deliver it.

Media and campaign framing. Traditional media, broadcast coverage and online campaigning all helped make Brexit the central frame. But the media did not invent the underlying cleavage: the 2016 referendum had already created powerful Leave and Remain identities. In AQA answers, treat media as a reinforcement and agenda-setting factor unless you have direct evidence of persuasion.

Policy consequences. The election immediately affected policy making. Johnson's majority allowed the Withdrawal Agreement Bill to pass and the UK left the EU on 31 January 2020. The election therefore links voting behaviour to policy outcome: a voting coalition built around Brexit produced a government able to implement Brexit.

AQA Judgement

The three elections show a clear development in UK voting behaviour.

ElectionStrongest factorOther important factorsBest judgement
1983Leadership, manifesto reputation and national context.Class voting, Falklands, opposition split, FPTP.Conservative victory was not only Thatcher's personal appeal; it also depended on Labour weakness and Alliance vote dispersion.
1997Party repositioning and Conservative unpopularity.Blair's leadership, professional campaign, media support, class dealignment.Labour won because it combined desire for change with reassurance about competence.
2019Brexit identity and campaign clarity.Johnson/Corbyn leadership contrast, age, education, class realignment, FPTP.Brexit was central, but it worked through leadership, class geography and party credibility.

In AQA answers, avoid three weak habits:

  • Do not say "class no longer matters" without nuance. It matters less in some elections, but class, education, housing and region still overlap.
  • Do not say "the media won the election" as a complete explanation. Media influence is difficult to isolate.
  • Do not list factors without connecting them to a result. A factor becomes analysis only when you show how it affected voters or seats.

For a 9-mark question, develop three clear points. For example: one point on class/age/education, one on leadership and campaign, and one on manifesto/media or Brexit. For a 25-mark essay, weigh factors against each other and end with a judgement about which factor was most important in the specific election named.
