Voting behaviour is about why people vote the way they do - the CAGER long-term factors (Class, Age, Gender, Ethnicity, Region) and the CLIMP short-term factors (Campaign events, Leadership, Issues, Manifesto, Polls). The spec asks you to know three case-study general elections in depth: one from 1945-92, the 1997 election, and one since 1997.
Tap a year. Watch which factor lights up - and which one fades. That swap is the realignment story in a single picture.
Pulzer's line "class is the basis of British politics, all else is embellishment" still holds. AB/C1 voters back the Conservatives; C2/DE voters back Labour. Age, gender and region produce small differences but Class is the master predictor.
Thatcher's breakthrough: she breaks the C2 skilled working-class vote, the so-called "C2 swing", but the underlying model is still class-based.
Class has fragmented. Working-class voters split between Labour and Reform. Middle-class voters split between Labour and Lib Dem. Class no longer predicts party choice.
The dominant cleavage is now age: under-30s lean Labour/Green by 40+ points; over-65s lean Conservative/Reform by 30+ points. The tipping point is around age 50.
Region has scrambled: Scotland is back to Labour after the SNP collapse; the Red Wall mostly returned to Labour but Reform won 5 seats in former Labour heartlands.
How to use it: Pick this LoA for the age-vs-class question type. Pick the CAGER/CLIMP balance line for the long-vs-short-term question.
Read the scenario. Tap the bubble that best explains it. Seven questions, mixed eras.
