Why do people vote the way they do? For decades the answer was class. Today it is a moving mix: age, education and region as the new long-term divides, and competence, leadership and issues deciding the final weeks. This walk-through covers the dealignment story, the long-term and short-term factors, the case-study elections, turnout, and the media debate - then finishes with a worked 30-mark essay. Three short quizzes break the tour up.
For most of the post-war period, British voting had a simple model. Pulzer's famous line - class is the basis of British politics, all else is embellishment - held: AB and C1 voters backed the Conservatives, C2 and DE voters backed Labour, and most voters stayed loyal to their party for life. That model has broken down in two linked processes: class dealignment, the weakening of the link between social class and party choice, and partisan dealignment, the decline of lifelong party loyalty since the 1970s. What replaced them is the subject of this topic: new long-term divides (above all age), short-term valence judgements about competence and leadership, and a media environment that has changed beyond recognition. The spec asks you to carry three case-study general elections - one from 1945-92, the 1997 election, and one since 1997 - and to explain their outcomes with both kinds of factor.
Scroll - each factor lights with its old pattern, its new pattern, and the evidence.
The long-term factors are the slow-moving social facts about a voter: Class, Age, Gender, Ethnicity, Region - the CAGER list, matching spec points P1.4.1.c and P1.4.1.d. The story across them is the same realignment told five ways: class has faded as the master predictor, and age has taken its place. Scroll through; the figure beside you holds the five factor cards with the one you are reading lit.
In 1979, class predicted the vote and the other four factors produced small differences. By 2024, class had fragmented and age had become the dominant divide. Learning each factor means learning both ends of that arc - the exam rewards the comparison, not the snapshot.
Class voting was the basis of the 1945-92 model. The first big crack came in 1979, when 41% of C2 skilled workers voted Conservative - up 11 points - helped by the Right to Buy offer. By 2019 the link was weaker than at any election since the war: working-class Leave-supporting seats in the North and Midlands went Conservative while middle-class Remain cities went Labour. In 2024 the fragmentation deepened: working-class voters split between Labour and Reform UK, middle-class voters between Labour and the Liberal Democrats.
In 1979 the age gap was modest. By 2019 it was the largest in modern UK polling: under-25s voted Labour by around 57% while over-65s voted Conservative by around 62%. In 2024 the gap stayed large: under-30s leaned heavily Labour and Green, over-65s split between Conservative and Reform, with the tipping point around age 50. The 2020 Pearson mark scheme treats this as the live debate - age as the clear correlation, but with a turnout caveat: younger voters turn out at far lower rates, so age by itself is an insufficient guide.
For decades women leaned marginally Conservative - even in 1979, the expected pull of a female Conservative leader made little difference either way. The shift came in 1997, when women moved decisively to Labour for the first time, narrowing the long-standing Conservative female lead. Since 2017 women have leaned slightly more Labour than men; in 2024 Reform under-performed with women relative to men. The gap has always been small - use gender as a supporting factor, never the headline.
Non-white voters backed Labour by roughly 80% in 1979, and the Labour lean has held in every election since - around 64% Labour to 20% Conservative in 2019, and heavily Labour again in 2024. But the picture varies by group: Hindu voters have been notably less Labour-leaning since 2019, and 2024 showed further Conservative slippage among South Asian voters even with a British Asian Prime Minister. The stability is the point - and so is the internal variation that complicates it.
The North-South divide formed in 1979 and became structural by 1983, with Labour confined to the industrial heartlands. 2019 redrew the map: Red Wall seats fell to the Conservatives - Bolsover, Workington, Sedgefield - while Scotland went almost entirely SNP (48 of 59 seats). 2024 scrambled it again: Scotland returned to Labour (37 of 57 seats after the SNP collapse), the Red Wall mostly came back, the Conservatives were squeezed into a blue wall of southern seats with the Liberal Democrats taking many of them, and Reform won Clacton and a handful of northern and coastal seats.
Every factor runs through turnout. Overall turnout has declined long-term since 1997 (71%); in 2024 it fell to 60.0%, the lowest at a general election since 2001 - and it is lower among young, working-class and ethnic-minority voters. That is why the 2020 mark scheme's caveat matters: a group's voting preference only shapes results if the group actually votes.
What decides the final weeks once long-term loyalty has loosened.
Partisan dealignment is what makes the short-term factors matter. When fewer voters are loyal for life, more of them decide late - and they decide on valence: judgements about which party is more competent to govern, rather than which party matches their class or ideology. The working mnemonic is CLIMP: Campaign, Leadership, Issues, Manifesto, Press and polls.
Campaigns can set the frame months out - the Saatchi and Saatchi "Labour Isn't Working" poster ran from August 1978 and shaped the 1979 race - or collapse in weeks, as the Conservatives' 2024 campaign did, from the rain-soaked announcement to the D-Day departure and the betting scandal. Leadership ratings are the sharpest valence measure: Thatcher was re-made for television by Gordon Reece in 1979 while Callaghan looked exhausted; Corbyn's ratings in 2019 were the lowest since YouGov records began and were cited by Red Wall canvassers as the single decisive factor in many fallen seats; in 2024 Starmer's personal ratings were low but he out-scored Sunak on "would make a good PM" - valence is relative.
Issues decide elections when one dominates: trade union power in 1979, Brexit in 2019 ("Get Brexit Done", repeated four to five times a minute on the doorstep), and in 2024 the NHS, the cost of living, immigration - and the strongest valence verdict since 1997: the Truss mini-budget of September 2022 had destroyed the Conservatives' reputation for economic competence in a single weekend. Manifestos matter most when they misfire: Labour's 1983 programme - nationalisation, EEC withdrawal, unilateral disarmament - was called "the longest suicide note in history", and the 2019 offer of free broadband and large-scale nationalisation was seen as too radical even by sympathetic voters. Polls shape campaigns through tactical voting and resource decisions - the Liberal Democrats' 2024 gains in the South depended heavily on tactical-voting polling.
Scroll - each election lights with its result, its story and the factors that explain it.
Spec point P1.4.1.a requires three case studies: one election from 1945-92, the 1997 election, and one since 1997. The Panther set covers 1979 and 1983 (the 1945-92 candidates), 1997, and 2019 and 2024 (the post-1997 candidates) - learn three in depth and keep the others as comparison material. Scroll through; the figure beside you holds the election cards.
From the end of the post-war consensus in 1979 to the realignment confirmed in 2024. For each election, carry four things: the headline result, the events behind it, the long-term CAGER picture, and the short-term CLIMP picture.
The Winter of Discontent was the backdrop: public-sector strikes, rubbish piling up, gravediggers refusing burials, and The Sun's "Crisis? What Crisis?" framing of a PM who never actually said it. The result ended the post-war Keynesian consensus and began 18 years of Conservative rule. The CAGER headline: class still ruled, but the C2 swing - 41% of skilled workers voting Conservative, up 11 points - started the long working-class drift, powered by Right to Buy. The CLIMP headline: the "Labour Isn't Working" poster, Thatcher's television coaching, trade union power as the dominant issue, and The Sun backing the Conservatives decisively for the first time.
Thatcher rode the Falklands wave while Labour tore itself apart - the 1981 SDP split, the Bennite left ascendant, and a Foot manifesto (nationalisation, EEC withdrawal, unilateral disarmament) that Gerald Kaufman called "the longest suicide note in history". The largest Conservative majority since 1935. The election that proves the FPTP point too: the Alliance's 25.4% of votes returned just 23 seats, because its support was spread too thinly to convert. The North-South divide became structural here.
The polls showed a Labour landslide for months and the result confirmed it - the standard evidence for the bandwagon effect. Two shifts make 1997 the hinge election. First, gender: women moved decisively to Labour for the first time, ending the long Conservative female lead. Second, the media: gaining the support of The Sun was pivotal for Labour - the 2022 Pearson mocks mark scheme uses exactly this example for press influence. And 1997 starts the modern turnout story: at 71%, it marks the beginning of the long-term decline that reached 60% in 2024.
Three years of Brexit deadlock - May's three lost meaningful votes, the unlawful prorogation, the Benn Act - ended in a single-issue election. Class realignment was extraordinary: C2DE Leave seats in the North and Midlands went Conservative while AB Remain cities went Labour; "Brexit voter" predicted choice better than "working class". The age gap hit its modern record. Red Wall seats fell - Bolsover, Workington, Sedgefield. CLIMP delivered the verdict: a ruthlessly disciplined "Get Brexit Done" message against a Labour campaign facing both ways, and Corbyn's record-low leader ratings.
Fourteen years, five Prime Ministers, and the Truss mini-budget crisis that destroyed the Conservative reputation for economic competence in a weekend. "Time for a change" was the most common doorstep response - the strongest valence verdict since 1997. The CAGER picture: class fragmentation deepened, the age gap stayed dominant, Scotland turned Labour after the SNP collapse, and Reform's strength among C2DE voters split the old Conservative coalition. The media moment: The Sun backed Labour for the first time since 1997. And the warning in the numbers: a 174-seat majority on a third of the vote, on the lowest turnout since 2001 - a broad coalition with soft commitment.
Never narrate an election - mine it. Each case study supplies evidence for a factor argument: 1979 for class and the press, 1983 for manifestos and FPTP distortion, 1997 for gender, the bandwagon and the Murdoch switch, 2019 for age and leadership, 2024 for valence and turnout. The 30-marker is about the factors; the elections are the proof.
Scroll - each part of the media debate lights with its evidence and its counter.
Spec point P1.4.2.a asks for an assessment of the role and impact of the media on politics, both during and between elections - including opinion polls, media bias and persuasion. The 2022 Pearson mocks mark scheme carries the full debate, and its question is the one to prepare: are election outcomes influenced more by the media than by any other factor? Scroll through the four parts of the answer.
The press, the broadcasters and social media work in different ways - one is openly partisan, one is neutral by law, one is targeted and unregulated. The question across all three: does the media change votes, or follow them?
Newspapers can openly back a party. The Murdoch press is the standard case: The Sun backed the Conservatives decisively in 1979; gaining its support was pivotal for Labour in 1997, as it was for Conservative fortunes in 2010 and through the 1980s (2022 mocks MS); and in 2024 it backed Labour for the first time since 1997. The 1983 campaign shows the personalised version: the Express's front-page attack on Foot is the textbook leader hit.
The counter: the press follows winners as much as it makes them - newspaper choice may reflect the reader's views rather than alter them (2020 MS), and by 2024 social media, broadcast and word-of-mouth had eroded press primacy.
Television and radio are required by law to be neutral - yet the 2022 mocks mark scheme insists their importance cannot be overestimated, because we live in a world of personality and sound bites. How a leader comes across on screen matters enormously, and a slip on broadcast media can be fatal: Thatcher was coached for television in 1979; Foot could not project authority in the broadcast age; Sunak's D-Day departure in 2024 became a story that ran for days at a critical moment.
The counter: neutrality rules mean broadcast influence works through performance, not persuasion - it amplifies a campaign's strengths and weaknesses rather than picking a side.
Social media reaches the younger voters who have the lowest turnout and are hardest for the traditional press to touch (2022 mocks MS). In 2019 the Conservatives dominated Facebook advertising spend with targeted micro-messaging in Red Wall seats; in 2024 Reform UK's social media strength matched the coverage of Farage personally. Parties have moved their money and effort there because they believe it works.
The counter: reaching low-turnout voters only matters if they vote - and 18-24 turnout remains the lowest of any group. Targeted reach is not the same as changed minds.
The 2022 mocks mark scheme's own framing of the agreement side is careful: studies indicate the media confirms and maintains existing electoral choices - reinforcement, not conversion. And its disagreement column lists the rivals: models based on class and social background; gender, age and region; the choice on offer in the manifestos; and the electoral system itself as the biggest factor in outcomes.
The strong essay line: the media frames and reinforces, but the deep factors and the system decide. The Sun has backed the winner in the big realignment elections - which is evidence it can read the public at least as much as evidence it leads them.
How the topic is tested, with approaches to the recurring questions.
Voting behaviour and the media appears in Paper 1 as a 30-mark question - at Q1 with a source, or at Q2 as an essay. Both split AO1/AO2/AO3 at 10/10/10. The rules: two views weighed in a balanced way with a sustained line of argument; a one-sided answer is capped at Level 2. Structure by theme, not by election - a chronological tour of three elections is the structure the examiners mark down. Conclusions justify rather than summarise, and post-2024 evidence is what 2026 sittings are expected to carry.
Recurring 30-mark questions to practise.
Approach: Pair the source points. Para 1 - age: the clear correlation (older more Conservative, younger more Labour) against the turnout caveat - younger voters turn out at far lower rates, so age alone is an insufficient guide. Para 2 - class and region: dealignment renders them an uncertain guide against the persistence of safe seats and political heartlands. Para 3 - the media: newspapers and social media as decisive factors against the reinforcement point - newspaper choice may reflect the reader's views rather than alter them. Side with the replacement view, with the turnout caveat as your concession.
Approach: The Part 4 debate is the plan. Para 1 - the press: the Murdoch record (1979, 1997, 2010, 2024) against reinforcement and declining reach. Para 2 - broadcast and social media: neutral-by-law power plus targeted reach against the turnout problem. Para 3 - the rivals: class and social background models, age and region, the manifesto offer - and the mark scheme's final disagreement point, that the electoral system itself is the biggest factor in outcomes. Judgement: the media frames; the deep factors and the system decide.
Approach: Theme by theme using paired evidence from the same elections. Para 1 - competence and leadership: the Truss legacy and 'time for a change' in 2024, Corbyn's ratings in 2019, against the age and region patterns that set each party's possible range. Para 2 - campaigns and manifestos: 'Get Brexit Done' and the 1983 suicide note against the evidence that campaigns mostly move voters within limits the demographics set. Para 3 - the linking concept: partisan dealignment is itself long-term, and it is what gives the short-term factors their power. Judgement: short-term factors decide late, but only inside the space the long-term factors leave open.
Approach: The signature post-2017 question - the worked essay below answers it in full.
Judgement. Age has replaced class as the most important influence on voting behaviour. Class built the post-war party system and its ghost survives in heartlands and turnout patterns, but it stopped predicting individual votes somewhere between 1979 and 2019. Age now does that work, and has done it through three elections under entirely different conditions. The honest qualification is the turnout caveat - age decides among those who vote, and the old vote more than the young - but a qualified king is still the king.
Class voting. The post-war pattern: AB/C1 voters Conservative, C2/DE voters Labour. Pulzer's line - class is the basis of British politics, all else is embellishment - summarised the 1945-92 era.
Class dealignment. The weakening of the link between social class and party choice - visible from the 1979 C2 swing onward, extreme by 2019, deeper still in 2024.
Partisan dealignment. The decline of lifelong party loyalty since the 1970s. The reason short-term factors and floating voters now decide elections.
Valence. Voting on judgements of governing competence rather than class or ideology. 2024 - the Truss legacy and 'time for a change' - is the strongest valence verdict since 1997.
CAGER. The long-term factors: Class, Age, Gender, Ethnicity, Region.
CLIMP. The short-term factors: Campaign, Leadership, Issues, Manifesto, Press and polls.
The age tipping point. The age at which voters switched from leaning Labour to leaning Conservative or Reform - around 50 in 2024.
The C2 swing. The 1979 movement of skilled working-class voters to the Conservatives - 41%, up 11 points - helped by Right to Buy. The first crack in class voting.
The Red Wall. Long-held Labour seats in the North and Midlands that fell to the Conservatives in 2019 (Bolsover, Workington, Sedgefield) and mostly returned to Labour in 2024.
Tactical voting. Backing a less-preferred candidate with a better chance of beating the candidate you oppose. The Liberal Democrats' 2024 southern gains relied on it heavily.
Turnout. 76% in 1979; 71% in 1997, where the long decline began; 67.3% in 2019; 60.0% in 2024 - the lowest since 2001, and lower among young, working-class and ethnic-minority voters.
Bandwagon effect. Voters moving toward the perceived likely winner - 1997, where the polls showed a Labour landslide for months and the result confirmed it, is the standard evidence.
Media reinforcement. The finding cited in the 2022 mocks mark scheme: the media confirms and maintains existing electoral choices rather than converting voters.
Broadcast neutrality. The legal requirement that UK television and radio stay neutral - the reason broadcast influence works through performance and coverage, not endorsement.
The Murdoch press. The standard press-influence case: The Sun backed the Conservatives in 1979 and through the 1980s, switched to Labour in 1997 ('pivotal' - 2022 mocks MS), backed the Conservatives in 2010, and returned to Labour in 2024.
